Trash Can Liner Types
Darren Kincaid - Tuesday, March 02, 2010
Resin
- Resin is the basic raw material used in manufacturing trash can
liners. The two basic types of resins utilized in trash can liner
manufacturing are High Density and Linear Low Density.
Linear Low Density Trash Can Liners
Linear Low Density can liners are made from high quality resins that are highly resistant to puncturing and tearing. The exceptional strength and stretch properties of Linear Low Density trash can liners make them a great option for kitchen trash that may include glass or sharp, irregularly shaped objects. Various resins that comprise Linear Low Density polyethylene include butane, hexene and metallocene.
For the environmentally conscious, we also carry a line of Biodegradable Low Density Trash Can Liners, which are manufactured with at least 60% recycled post industrial scrap plus a degradable additive.
High Density Trash Can Liners
High Density can liners are made from high molecular density resins. High Density trash can liners are great for the office, restroom, or any type of trash that does not include sharp edges. High Density trash can liners are also less expensive per unit than low density trash can liners.
Some important definitions are as follows:
Gauge - Gauge is a term used in the trash can liner industry to describe the thickness of a liner. Gauge is typically stated either in mils or microns.
Mil - A mil is a measurement based on a thousandth of an inch (.001). Linear Low Density trash can liners will range from .30 to 2.0 mils. Improved resin technologies have allowed manufacturers to produce thinner trash can liners that are much stronger than the trash can liners of the past.
Micron - A micron is a measurement based on one hundred thousandths of an inch (.00001). High Density trash can liners range from 6 to 24 microns.

Anti Static Bags - ESD - Metallic Shielding
Darren Kincaid - Tuesday, February 23, 2010
Atlantic
Poly has an large supply of anti static ESD bags in stock and ready to
ship for electronics packaging (pc board, component and module level)
and cleanroom environments (hi-rel and military). We have a wide variety
of ESD packaging products such as static shielding bags, conductive
tubing, cushioned (bubble) bags for transport of delicate electronics,
and anti-static bags. Most of our ESD bags are available in a variety of
shapes, sizes and colors. Choices of our static shielding and
anti-static bags include open top, metal-in shielding and ziplock.
Depending on your application we are sure ot have an anti-static bag ot
meet your needs.
Anti-static bags reduce the threat of damage to electronic components by incedental static or electrical discharge. One of the main advantages of packaging in a plastic bag is that they are easily sealable using a heat sealer or come in ziplock form.

Benefits of Plastic Trash Can Liners
Darren Kincaid - Monday, February 15, 2010
The main benefits of trash can liners are twofold. Plastic liners
are more flexible and durable than other materials, that provide a
better moisture and chemical barrier, and offer higher resistance to
tear propagation. Trash can liners
are typically made from linear low density polyethylene for superior
tensile strength and tear resistance. Lightweight, but strong and
durable, poly trash can liners
make it possible to move and store more waste than ever before. And
because of their advanced resistance to tearing and leaking, these
liners make it possible to handle waste and other hazardous material
without any threat to the surrounding environment.

Poly Bags are practical for many uses in many different industries
Darren Kincaid - Tuesday, February 02, 2010
Are
you looking for a certain types of bags which are practical for almost
all types of items? Do you prefer to have bags that you can reuse and
recycle from time to time? You should consider the polyethylene bags, commonly known as poly bags or plastic bags
. Many industries use these bags due to wide variety of types
available, ease of use and efficiency. They are frequently used in
industries related to fabrics, apparels, electronics, foods, and the
like to protect items from dust, dirt, and moisture.
Poly bags come in many different types in order to manage the variety of functions they are needed for. Among the more common and popular types are the flat, gusseted, and re-closable poly bags.
The most popular type among all the poly bags is the flat poly bag. They are used in industries like agriculture and landscaping, hospitals, banks, and electronics. Primary use examples are in the areas of electronics manufacturing and computer software shipping. Other industries includes mail order businesses and the like. Once the items are placed inside the flat poly bags, the bags are sealed through heating or through taping. There are also some instances when the bags are twist-tied to be closed.

PRINTING ON PLASTIC BAGS
Darren Kincaid - Monday, January 25, 2010
All Atlantic Poly plastic bags are printed
using a method called Flexographic Printing. Flexographic printing uses
flexible rubber printing plates which are adhered to a cylinder. The
inked plates with a slightly raised image are rotated on the cylinder
and the image is transferred to the plastic sheet or bag. All of our
inks are water based and are environmentally friendly. We can print up
to 8 colors on 2 sides.
Printing on a poly bag obviously adds to the cost of the bag. We can imprint as few as 5000 bags but the cost is much higher because of the set-up. (We find that for cost optimization runs of 25,000 or more are more cost efficient)
There is an initial cost for plates but the customer maintains ownership of the plates. These plates are compatible with most printing presses.We also have several graphic designers available to help with the design of your bag.

Plastic Pricing Keeps Going Up!
Darren Kincaid - Wednesday, January 20, 2010
PRICING ON ITS WAY UP !!
We have been advised that our polyethylene resin suppliers have implemented their previously announced .05/lb increase which will go into affect on Feb. 1, 2010 (This brings the total resin increases implemented since January of last year to over .21/lb). Our suppliers are citing continued export volumes, extremely low inventories throughout the supply chain, high operating rates, and rising costs on feed stocks as the main reason for the increases. Please be assured we will continue to support our loyal customers and continue to minimize the impact that these increases have on your business.

Recylced Bags - What are they really?
Darren Kincaid - Saturday, January 09, 2010
RECYCLED BAGS
What is a recycled bag?
Blending recycled resin with virgin resin creates a recycled content
bag. There are currently no guidelines in place stating what a “decent”
blend would be. Making a 100% recycled bag is not recommended because
doing this would compromise the strength of the bag. Our recycled bags
are normally mfg. from a 30/70 blend. (30% Recycled/70% Virgin) The
recycled content can consist of one of two different types of
feedstock…post industrial scrap**(See Below) or post consumer scrap.**
In theory, a “recycled bag” should cost less than a “virgin grade bag”
but, because of a fluctuating market this isn’t always the case. (The
scrap still has to be processed, cleaned and mfg. into a usable form)
Also, recycled bags tend to be cloudier and must be mfg. from at least
.0015 thickness to maintain strength.
Customers have also
inquired about printing the Recycling Logo on the bags. This can be
done, and we do it for many of our customers but it does become a
“custom” run and adds to the expense of the bag.
BIOGEGRADABLE PLASTICS are not all equal or good for the environment
Darren Kincaid - Monday, January 04, 2010
BIOGEGRADABLE PLASTICS
Biodegradability is an issue we’ve been involved with for the past several years. We urge you to read the following paragraphs to better understand what it involves. Currently we run both types of biodegradable bags (Oxo or Hydro). There is a shelf life with these bags so we currently do not have a stocking program. Please contact us to help implement a “Green” program for your company.
Types of Biodegradable Plastics - It is important to distinguish between the different types of biodegradable plastic, as their costs and uses are very different. The two main types are oxo-biodegradable and hydro-biodegradable. In both cases degradation begins with a chemical process (oxidation and hydrolysis respectively), followed by a biological process. Both types emit CO2 as they degrade, but hydro-biodegradable can also emit methane. Both types are compostable, but only oxo-biodegradable can be economically recycled. Hydro-biodegradable is much more expensive than oxo-biodegradable.
OXO-BIODEGRADABLE PLASTIC - This new technology produces plastic which degrades by a process of OXO-degradation. The technology is based on a very small amount of pro-degradant additive being introduced into the manufacturing process, thereby changing the behaviour of the plastic. Degradation begins when the programmed service life is over (as controlled by the additive formulation) and the product is no longer required.
There is an additional cost involved in products made with this technology, which can be made with the same machinery and workforce as conventional plastic products.
The plastic does not just fragment, but will be consumed by bacteria and fungi after the additive has reduced the molecular structure to a level which permits living micro-organisms access to the carbon and hydrogen. It is therefore “biodegradable.” This process continues until the material has biodegraded to nothing more than CO2, water, and humus, and it does not leave fragments of petro-polymers in the soil. Oxo-biodegradable plastic passes all the usual ecotoxicity tests, including seed germination, plant growth and organism survival (daphnia, earthworms) tests carried out in accordance with ON S 2200 and ON S 2300 national standards.
The length of time it takes for oxo-biodegradable products to degrade can be ‘programmed’ at the time of manufacture and can be as little as a few months or as much as a few years. They are protected from degradation by special antioxidants until ready for use, and storage-life will be extended if the products are kept in cool, dark conditions.
Unlike PVC, the polymers from which oxo-biodegradable plastics are made do not contain organo-chlorine. Nor do oxo-biodegradable polymers contain PCBs, nor do they emit methane or nitrous oxide even under anaerobic conditions.
HYDRO-BIODEGRADABLE PLASTICS - Hydro-biodegradation is initiated by hydrolysis. Some plastics in this category have a high starch content and it is sometimes said that this justifies the claim that they are made from renewable resources. However, many of them contain up to 50% of synthetic plastic derived from oil, and others (e.g. some aliphatic polyesters) are entirely based on oil-derived intermediates. Genetically-modified crops may also have been used in the manufacture of hydro-biodegradable plastics.
Hydro-biodegradable plastics are not genuinely “renewable” because the process of making them from crops is itself a significant user of fossil-fuel energy and a producer therefore of greenhouse gases. Fossil fuels are burned in the autoclaves used to ferment and polymerise material synthesized from biochemically produced intermediates (e.g. polylactic acid from carbohydrates etc); and by the agricultural machinery and road vehicles employed; also by the manufacture and transport of fertilizers and pesticides. They are sometimes described as made from “non-food” crops, but are in fact usually made from food crops.
A disproportionate amount of land would be required to produce sufficient raw material to replace conventional plastic products, and a huge amount of water, which is in such short supply in so many parts of the world.
Residues from some native starches can be seriously toxic; bitter cassava for example (tapioca) has a high level of hydro-cyanic glucoside present, which has to be removed by careful washing. During growth the plant is toxic to wildlife. Cassava is exhaustive of potash .
Three recent articles in the international press have drawn attention to the danger of using “renewable” resources derived from plants as a substitute for petroleum products. They focus on the use of corn and palm oil to make “biofuels” for motor vehicles, but the same danger arises from the use of corn and other agricultural products to make hydro-biodegradable plastics.
The International Herald Tribune wrote on 31st January 2007 “Just a few years ago politicians and green groups in the Netherlands were thrilled by the country’s adoption of “sustainable energy” by coaxing electricity plants to use biofuel. Spurred by government subsidies, energy companies designed generators that ran exclusively on this fuel, which in theory would be cleaner than fossil fuels because it is derived from plants.
Plastics made from crops, are up to 400% more expensive, they are not strong enough for use in high-speed machinery, and they emit methane (a powerful greenhouse gas) in landfill. Also, it is wrong to use land, water and fertilizers to grow crops for bioplastics and biofuels, which drives up the cost of food for the poorest people
Business Week 5 Feb 2007 edition “The rise in the price of corn that's hurting US pig farmers isn't caused by any big dip in the overall supply. In the U.S., last year's harvest was 10.5 billion bushels, the third-largest crop ever. But instead of going into the mouths of pigs or cattle or people, an increasing slice is being transformed into fuel for cars. The roughly 5 billion gallons of ethanol made in 2006 by 112 U.S. plants consumed nearly one-fifth of the corn crop.” US chicken producers are also being hit. The industry's feed costs are already up $1.5 billion per year. Ultimately, these increases will be passed on to consumers, and there could be dramatic inflation in food costs.
Oxo-bio plastics degrade in the upper layers of a landfill, but they are completely inert deeper in the landfill in the absence of oxygen. They do not emit methane at any stage.
Paper bags use 300% more energy to produce, they are bulky and heavy and are not strong enough, especially when wet. They will also emit methane in landfill.
