Roll Off Dumpster Liners Protect People and the Environment

Joseph Coupal - Friday, September 06, 2013

Basically, dumpster liners are massive garbage bags. Of course they are a bit more complicated than that, they differ in size, color, thickness and uses. Different companies have different needs that demand different dumpster liner requirements.

Dumpster liners are the easiest most versatile solution for every industry in order to provide an extra level of protection for hazardous waste or to just better contain waste.  Concrete companies, asbestos abatement companies, environmental service companies and many more rely on roll-off dumpster liners to contain materials which may be harmful to people or the environment.

Roll-off dumpster liners have many purposes. Mainly they offer protections against damaging spills, seepage and overflow. The dumpster liners shorten clean up time by keeping waste more easily contained.

Because dumpster liners act as a barrier between a dumpster and its contents, they must need to be made in various gauges to maintain integrity and protect from contamination. Dumpster liners also reduce potential leakage, lower wash-out costs and increase dumpster longevity.  They are naturally resistant to water, oil, grease, and most chemicals, and they are designed to resist punctures, tears and abrasions.  For a quote, contact Atlantic Poly.



Plastic Grocery Bags or Paper Grocery Bags?

Joseph Coupal - Tuesday, August 20, 2013

Are grocery bags made other materials such as paper or compostable plastics really better for the environment than traditional plastic grocery bags? There is no conclusive evidence supporting the argument that banning single use plastic bags in favor of paper bags will reduce litter, decrease the country’s dependence on oil, or lower the quantities of solid waste going to landfills. In addition, there is limited information on the environmental attributes of compostable plastics and how they fare against traditional plastic grocery bags or paper bags.

So, in order to glean information on the environmental impacts of grocery bags, the Progressive Bag Alliance contracted with Boustead Consulting & Associates (BCAL) to conduct a life cycle assessment on three types of grocery bags:

  • a traditional grocery bag made from polyethylene,
  • a grocery bag made from compostable plastics (a blend of 65% EcoFlex, 10% polylactic acid or PLA, and 25% calcium carbonate),
  • and a paper grocery bag made using at least 30% recycled fibers.

The life cycle assessment factored in every step of the manufacturing, distribution, and disposal stages of these grocery bags.

The results show that single use plastic bags made from polyethylene have many advantages over both compostable plastic bags and paper bags made with a minimum of 30% recycled fiber.

When compared to 30% recycled fiber paper bags, polyethylene grocery bags use less energy in terms of fuels for manufacturing, less oil, and less potable water. In addition, polyethylene plastic grocery bags emit fewer global warming gases, less acid rain emissions, and less solid wastes. The same exists when comparing the typical polyethylene grocery bag to grocery bags made with compostable plastic resins— traditional plastic grocery bags use less energy in terms of fuels for manufacturing, less oil, and less potable water, and emit fewer global warming gases, less acid rain emissions, and less solid wastes.

The findings of this study were peer reviewed by an independent third party to ensure that the results are reliable and repeatable. The results support the conclusion that any decision to ban traditional polyethylene plastic grocery bags in favor of bags made from alternative materials will result in a significant increase in environmental impacts across a number of categories from global warming effects to the use of precious potable water resources. As a result, consumers should re-evaluate decisions to use or ban traditional plastic grocery bags, as the unintended consequences can be significant and long-lasting.

Plastics Glossary of Terms- Atlantic Poly

Joseph Coupal - Monday, July 29, 2013

If you deal in plastics or need them in your business, there are some terms you will need to know. Over the last few blog posts, Atlantic Poly, a plastic bag and products company in MA, has been  acquainting you with some of the more necessary plastics terms. Here are the last few...

Pellets: Tablets of uniform size, consisting of resins or mixtures of resins with compounding additives which have been prepared for molding operations by shaping in a pelletizing machine or by extrusion and chopping into short segments.

Perforating: Processes by which plastic film or sheeting is provided with holes ranging from relatively large diameters for decorative effects (by means of punching or clicking) to very small, even invisible, sizes. The latter are attained by passing the material between rollers or plates, one of which is equipped with closely spaced fine needles or by spark erosion.

Permeation: The passage or diffusion of a gas, vapor, liquid, or solid through a barrier without physically or chemically affecting it.

Permeability: Permeability is the property of a material, i.e. the degree to which it allows permeation to occur.

Photodegradation: Degradation of plastics due to the action of light. Most plastics tend to absorb high-energy radiation in the ultraviolet portion of the spectrum, which results in the formation of free radicals and causes oxidation, cleavage, and other degradative reactions.

Polyethylene: A family of resins obtained by polymerizing the gas ethylene.

Polymer Process Aid (PPA): Additives incorporated into plastics as a modifier to aid in the extrusion of film, pipe, sheet, etc.

Polymerization: A chemical reaction in which the molecules of a simple substance (monomer) are linked together to form large molecules whose molecular weight is a multiple of that of the monomer.

Polyolefins: The class of polymers made by polymerizing relatively simple olefins, including ethylene, propylene, butenes, isoprenes, and pentenes.

Polypropylene: A tough, lightweight, rigid plastic made by the polymerization of high-purity propylene gas in the presence of an organometallic catalyst at relatively low pressures and temperatures.

Pressure Roll: In extrusion coating, a roll used to apply pressure to consolidate the substrate and the plastic film with which it has been coated.

Random Copolymer: A copolymer consisting of alternating segments of two monomeric units of random distribution, including single molecules.

Resin: An organic substance of natural or synthetic origin characterized by being polymeric in nature.

Screen: Woven metal screens are installed across the flow of plastic in an extruder. They are located between the tip of the screw and the die. Supported by a breaker plate, the screens strain out contaminants and increase back pressure.

Sheeting: Sheets are distinguished from films in the plastics and packaging industry only according to the thickness. A web under 10 mils (.010 inch) thick is usually called a film, whereas a web 10 mils and over in thickness is usually called a sheet. Sheeting is most commonly made by extrusion, casting, and calendering.

Slip Agent: Provides surface lubrication following the processing of plastics. Compounded into the plastic, the additive gradually migrates to the surface where it reduces the coefficient of friction. Slitting: THe conversion of a given width of plastic film, tube, or sheeting to several various widths by means of knives.

Specific Gravity: The ratio of weight of a given volume of a substance to that of an equal volume of water at the same temperature. The temperature selected varies among industries, 15°C (60°F) being the usual standard.

Specific Heat: THe amount of heat required to raise a specified mass by one unit of a specified temperature, usually expressed as Btu/lb/°F. or cal/g/°C.

Stabilizer: Ingredient used in the formulation of some polymers to assist in maintaining the physical and chemical properties of the compounded materials, for example, heat and UV stabilizers.

Static Eliminators: Mechanical devices for removing electrical static charges from plastic articles. Types of static eliminators include static bars, ionizing blowers, and air guns.

Stress: The force producing or tending to produce deformation divided by the area over which the force is applied.

Surface Tension: A fluid in contact with a surface exhibits phenomena, due to molecular attractions, which appears to arise from a tension in the surface of the fluid. It may be expressed as dynes per centimeter or as ergs per square centimeter.

Tack: The stickiness of an adhesive, measurable as the force required to separate an adherent from it by viscous or plastic flow of the adhesive.

Tackifier: A substance such as a resin ester which is added to synthetic resins or elastomeric adhesives to improve the initial and extended tackiness of the film.

Glossary of Plastics Terms Continued...

Joseph Coupal - Monday, July 22, 2013

If you deal in plastics or need them in your business, there are some terms you will need to know. Over the next few blog posts, Atlantic Poly, a plastic bag and products company in MA, would like to acquaint you with some of the more necessary plastics terms. The last two weeks we listed some of the terms, here are  few more...

Foam: Process for producing plastic sheet or molded article with a cellular construction. Either a chemical or gaseous blowing agent is introduced into the polymer melt while the melt is being prepared in the extruder barrel. As the plastic melt exits the die, it expands a predetermined amount forming a cellular wall.

Film: Sheet material having a nominal thickness not greater than 10 mil.

Flame Retardant: Reactive compounds and additive compounds to render a polymer fire resistant. Reactive compounds become an integral part of the polymer.

Gauge: Thickness of plastic film measured in decimal inches or mils.

Gel: Small globular mass which as not blended completely into the surrounding material resulting in a fault in the film or sheet.

Glass Transition Temperature: The temperature at which a reversible change occurs in an amorphous polymer when it is heated to a certain temperature and undergoes a rather sudden transition from a hard, glassy, or brittle condition to a flexible or elastomeric condition.

Gloss: Brightness or luster of a plastic resulting from a smooth surface.

Gravure Printing: The depressions in an engraved printing cylinder or plate are filled with ink, the excess raised portions being wiped off by a doctor blade. Ink remaining in the depressions is deposited on the plastic film or other substrates as it passes between the gravure roll and resilient back-up roll.

Haze: Cloudiness in plastic film. Measured as percent haze, anything below 5 percent is generally considered high clarity.

Heat Sealing: The process of joining two or more thermoplastic films or sheets by heating areas in contact with each other to the temperature at which fusion occurs, usually aided by pressure.

High-Density Polyethylene: This term is generally considered to include polyethylene's ranging in density from about 0.940 to 0.960 and over.

Homopolymer: The result of the polymerization of a single monomer, a homopolymer consists of a single type of repeating unit.

Jfold: Folding of a film along the length to obtain a two layered product with one layer wider than the other.

Lamination: Bonding of a polymeric or non-polymeric substrate to a polymeric film using heat and pressure.

Low-Density Polyethylene: This term is generally considered to include polyethylene's ranging in density from about 0.915 to 0.925. In low density polyethylene's, the ethylene monomeric units are linked in random fashion, with the main chains having long and short side branches. This branching prevents the formation of a closely knit pattern, resulting in material that is relatively soft, flexible and tough, and which will withstand moderate heat.

Masterbatch: A concentrated blend of pigment, additives, filler, etc. in a base polymer.

Melt Fracture: Is a phenomenon of melt extrudate in which the surface appears rough or wavy upon exit from the die. Melt fracture may appear uniformly or in certain sections only.

More Plastics Glossary Terms - Atlantic Poly

Joseph Coupal - Monday, July 15, 2013

If you deal in plastics, as in manufacture them, sell them, use them, order them or need them in your business, there are some terms you will need to know. Over the next few blog posts, Atlantic Poly, a plastic bag and products company in MA, would like to acquaint you with some of the more necessary plastics terms. Last week we listed some of the terms, here are  few more….

Calcium Carbonate: A filler and extender used in thermoplastics. It occurs naturally in the form of minerals such as calcite, chalk, limestone, marble, and whiting.

Cast: The cast film process involves the extrusion of molten polymers through a flat slot die to form a thin film or sheet. This film of molten polymer is then quenched by passing through a set of chill rolls (typically water-cooled). The film quenches immediately, and the edges are trimmed prior to winding or stacking.

Centerfold: Folding a film along the length to obtain a two layered product with half the width.

Cfold: Folding of a film along the length to obtain a two layered product with flaps folded on each side of the folded product. The folded film profile looks like a stapled pin from a stapler.

Chill Roll: A cored roll, usually temperature controlled with circulating water, which cools a molten polymer web on contact before winding.

Coextrusion: Fabrication of a multi-layer film by pumping materials through separate extruders and then merging the extruded material into a common die assembly. These die assemblies are constructed to maintain distinct material layers with fusion occurring at the boundaries due to the pressures and temperature of the extruded material.

Color Concentrate: A plastics compound which contains a high percentage of pigment to be blended into base resins. The term masterbatch is sometimes used for color concentrate as well as for concentration of other additives. Comonomer: A monomer which copolymerizes with another monomer.

Copolymer: A polymer resulting from the polymerization reaction of two chemically different monomers.

Corona Treat: The process by which the surface energy of plastic films, foils and paper is increased in order to allow improved wettability and adhesion to inks, coatings and adhesives.

Degradation: A deleterious change in the chemical structure, physical properties, or appearance of a plastic caused by exposure to heat, light, oxygen, or weathering.

Density: Weight per unit volume of a substance usually reported in g/cm3 or lb/ft3.

Die: A steel block containing an orifice through which plastic is extruded, shaping the extrudate to the desired form.

Die Gap: Distance between the metal faces forming the die opening.

Die Lines: Vertical or horizontal marks on the extrudate and in the finished product caused by damaged die elements or by contamination held up in the die land.

Differential Scanning Calorimetry (DSC): Method used to determine thermal histories of polymers such as melting points and glass transition points.

Drawdown: In extrusion, the process of pulling the extrudate away from the die at a linear speed higher than that at which the melt is emerging from the die, thus reducing the cross-sectional dimensions of the extrudate.

Elasticity: The property (of plastic materials) of recovering original size and shape after deformation.

Elastomer: A material which, at room temperature, can be stretched under low stress to at least twice its original length and, upon immediate release of the stress, will return with force to its approximate original length.

Elongation: Deformation caused by stretching; the fractional increase in length of a material stressed in tension.

Embossing: The process used to modify the surface texture of a smooth film to achieve special surface properties such as surface area, coefficient of friction, gloss, adhesion, etc., and alter the bulk density of the film. For example, embossing forms a waffle from a pancake.

Erucamide: A fatty acid-based slip additive used in polyolefin resins.

Ethylene Vinyl Acetate (EVA): Copolymeric member of the polyolefin family derived from random copolymerization of vinyl acetate and ethylene.

Extruder, Single Screw: Basic machine consists of a screw, barrel, drive mechanism, resin feed arrangement and controls. The constantly turning screw augers the resin through the heated barrel where it is heated to proper temperature and blended into a homogeneous melt. Before the melt can leave the barrel, it must pass through a breaker plate and screen pack. The melt is then extruded through the die into the desired shape.

Extrusion: Compacting and melting a plastic material and forcing it through an orifice in a continuous fashion.

Blown Film: Process involves extruding a continuous thin walled tube of plastic and inflating it immediately after it leaves the die. The pressure is such that the tube stretches, increasing its diameter and reducing its wall thickness to desired gauge. Air is trapped within the blow tube (bubble) between the die and collapsing rolls which convert it to layflat film to facilitate winding onto a roll.

Cast Film: Process by which a polymer is extruded from a slot die onto the surface of a water-cooled roll. Film is clearer and has more sparkle than blown film.

Coating: Coating of a substrate by extruding a thin film of molten polymer and pressing it onto the substrate.

Glossary of Plastics Terms

Joseph Coupal - Tuesday, July 09, 2013

If you deal in plastics, as in manufacture them, sell them, use them, order them or need them in your business, there are some terms you will need to know. Over the next few blog posts, Atlantic Poly, a plastic bag and products company in MA, would like to acquaint you with some of the more necessary plastics terms.

Additive: A compound or substance added to a polymer to improve or alter some characteristic of the polymer. Examples include pigments, antistats and flame retardant.

Antiblock Agent: Additive incorporated in film to prevent the adhesion (sticking) between touching layers of film during fabrication, storage, or use.

Antioxidant: An additive which inhibits the degradation and oxidation of material when exposed to ambient air during processing and subsequently in the end product form.

Antistatic Agent: Additive which imparts a slight degree of electrical conductivity to plastics, permitting the dissipation of static electricity.

Average Molecular Weight: Molecular weight of polymers is determined by viscosity of the material in solution at a specific temperature. This results in an average molecular weight of the molecular chains independent of specific chain length. The value obtained falls between weight and number average molecular weight.

Banbury Mixer: A compounding apparatus consisting of two contra-rotating spiral-shaped blades encased in intersecting cylindrical housings so as to leave a ridge between blades.

Barrel: The tubular portion of the extruder or injection molding machine in which the extruder screw is placed and rotates.

Beta Gauge: A thickness measuring device used for sheeting or extruded pans. The device operates by beta radiation being emitted on one side of the pan and a detector placed on the opposite side. When a pan is passed through the beam, some of the beta radiation is absorbed, which is indicative of the pan thickness.

Biaxial Orientation: The process of stretching a hot plastic film or other article in two directions under conditions resulting in molecular orientation in two directions.

Biodegradation: The degradation of plastics by microorganisms when buried in the soil. Some plastics can be modified to become biodegradable by the incorporation of a biodegradable additive such as corn starch.

The Benefits of Using Polyurethane Products

Joseph Coupal - Saturday, June 29, 2013

Have you ever taken the time to consider the advantages of using polyurethane products as opposed to alternative plastic or rubber products?

  • Polyurethane has excellent abrasion resistance and has out performed ordinary rubber and plastic sometimes by a factor of as much as 8 to 1
  • Polyurethane has significantly better impact resistance than structural plastics.  So why buy bubble pack made of any other product?
  • The physical properties of polyurethane are very resistant to environmental conditions such as heat, cold, and aging.  This makes our products perfect for roll-off liner bins.
  • Polyurethane has excellent long term stability in water and is resistant to swelling and deterioration in temperatures as high as 80ºC. It is also very resistant to mold, mildew and fungus growth, which make is it an excellent choice for applications in which there is exposure to a moist environment.
  • Polyurethane is resistant to oil and solvents and outperforms metal in chemical resistance. It is also resistant to radiation and is stable under high vacuum conditions. Protect both your products and industrial capital equipment via our large assortment of polyethylene roll stock.
  • Polyurethane can be used to reduce noise levels in manufacturing facilities. By having machinery such as ductwork and feed chutes lined with polyurethane, clatter and banging will be reduced.
