Details You Have To Learn About Polyethylene Packaging 101



Resins... Film thickness... Tensile strength... Impact resistance... Exactly what do these terms mean to you personally when selecting your polyethylene bags?

If you're not a poly salesman or have a diploma in Plastics Engineering, the terminology used in the market probably makes your face spin. To help you out, we've created Polyethylene Packaging 101.

Resins (Thought as: Some of numerous physically similar polymerized synthetics or chemically modified natural resins including thermoplastic materials including polyvinyl, polystyrene, and polyethylene and thermosetting materials such as polyesters, epoxies, and silicones that are used in combination with fillers, stabilizers, pigments, and other components to create plastics.)

Some find it overwhelming with all the different resins available nowadays. Would you choose when you have octene, metalocene, butene, hexene, etc... An educated sales representative should be able to help figure out what grade to make use of. Each grade has different characteristics and choices needs to be depending on applications. Understanding resin properties is important in formulating the proper product for your specific application.

Film Thickness (Gauge)

Polyethylene film thickness is measured by thousandths of an inch, or milli-inch. The thickness from the bag doesn't always correlate into strength. A whopping gauge bag is not always strong. Frequently it's a combination of resin grade and gauge in accordance with the application. A couple mil octene linear bag can have more strength than a 2 mil butene linear.

Tensile Strength vs. Impact Resistance

Tensile strength could be the maximum stress which a material can withstand while being stretched or pulled before breaking. Why so much interest?

You need to have a plastic bag that is strong enough for your application. A plastic bag that holds 50 pounds of material should have adequate tensile strength, otherwise the bag will end up breaking.

Impact resistance is often a material's power to resist shock loading. What does this implies?

Basically it's the film's capacity to resist being punctured. A punctured bag may result in contaminated goods or product loss.

When choosing the proper gauge and resin formula it is very important consider how tensile strength and impact resistance are relevant to your packaging application. An illustration which everybody can relate with is a garbage bag. I'm certain they have got had failure in a garbage bag whether or not this breaks when lifting out of your can (tensile strength) or waste material punctures holes in it (impact resistance). Effortlessly these variables in selecting the right formula on your polyethylene package, using a knowledgeable salesman is important.

Isn't there were a great deal to understand making Polyethylene "Film and Bags"!?!
