Points You Have To Understand About Polyethylene Packaging 101
Resins... Film thickness... Tensile strength... Impact resistance... Exactly what do many of these terms mean to you when purchasing your polyethylene bags?
Unless you are a poly salesman or have a degree in Plastics Engineering, the terminology used in a probably makes your brain spin. To help you, we've created Polyethylene Packaging 101.
Resins (Thought as: Any of numerous physically similar polymerized synthetics or chemically modified natural resins including thermoplastic materials such as polyvinyl, polystyrene, and polyethylene and thermosetting materials like polyesters, epoxies, and silicones which are combined with fillers, stabilizers, pigments, and other components in order to create plastics.)
It may seem overwhelming with the different resins available today. How do you choose for those who have octene, metalocene, butene, hexene, etc... A qualified salesman should be able to help figure out what grade to utilize. Each grade has different characteristics and choices must be based on applications. Understanding resin properties is crucial in formulating the proper product to your specific application.
Film Thickness (Gauge)

Film Thickness (Gauge)
Polyethylene film thickness is measured by thousandths of an inch, or milli-inch. The thickness of the bag doesn't necessarily correlate into strength. A heavy gauge bag is not always strong. Usually it's a combination of resin grade and gauge when compared with the applying. A couple mil octene linear bag could have more strength than a 2 mil butene linear.
Tensile Strength vs. Impact Resistance
Tensile strength may be the maximum stress that a material can withstand while being stretched or pulled before breaking. Why so much interest?
It's important to have a plastic bag that's sufficiently strong enough to your application. A plastic bag that holds 50 pounds of cloth should have adequate tensile strength, otherwise the bag will end up breaking.
Impact resistance is often a material's capability to resist shock loading. Precisely what does this suggest?
Basically oahu is the film's capacity to resist being punctured. A punctured bag could lead to contaminated goods or product loss.
When scouting for the proper gauge and resin formula it is important to consider how tensile strength and impact resistance are strongly related your packaging application. An example that can relate to can be a garbage bag. I'm sure they've got had failure inside a garbage bag if it breaks when lifting out from the can (tensile strength) or waste punctures holes within it (impact resistance). Effortlessly these variables in choosing the proper formula for your polyethylene package, developing a knowledgeable salesman is vital.
