Trash Can Liner Types
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
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.

Disposable Polyethylene Liners for Roll-Off's, Dump Trailers and Railroad Gondola Cars - Our heavy-duty bag liners are made from a combination of virgin and recycled polyethylene. Our unique patented form fit design virtually eliminates tearing and puts three thicknesses of plastic at the bottom of the container's tailgate for added leak protection. These liners are ideal for transporting bulk solids and sludges, and provide more protection than using film or film envelopes. A wide selection of bag liners is stocked for immediate shipment or custom liners can be manufactured to your specifications. Liner prices vary according to the length of the container, height of the liner, mil thickness of the liner, and material used.
Poly Bags are practical for many uses in many different industries
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
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!
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?
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.
