    Resins… Film thickness… Tensile strength… Impact resistance… What can most of these terms mean for you when buying your polyethylene bags?

    If you aren’t a poly salesman or have a college degree in Plastics Engineering, the terminology found in the market probably makes your brain spin. To help you out, we’ve created Polyethylene Packaging 101.

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

    It may seem overwhelming with all the current different resins available. How does one choose if you have octene, metalocene, butene, hexene, etc… A knowledgeable salesman can help know what grade to make use of. Each grade has different characteristics and choices ought to be according to applications. Understanding resin properties is critical in formulating the proper product on your specific application.

    Film Thickness (Gauge)

    Polyethylene film thickness is measured by thousandths inch, or milli-inch. The thickness of the bag doesn’t necessarily correlate into strength. Huge gauge bag may not be strong. Generally it is a mix of resin grade and gauge compared to the applying. A two mil octene linear bag will have more strength than the usual 2 mil butene linear.

    Tensile Strength vs. Impact Resistance

    Tensile strength is the maximum stress a material can withstand while being stretched or pulled before breaking. Why is this important?

    It’s important to have a very plastic bag that’s sufficiently strong for the application. A plastic bag that holds 50 pounds of fabric have to have adequate tensile strength, otherwise the bag find yourself breaking.

    Impact resistance can be a material’s capability to resist shock loading. Simply what does this implies?

    Basically oahu is the film’s power to resist being punctured. A punctured bag may result in contaminated goods or product loss.

    In choosing the correct gauge and resin formula you will need to consider how tensile strength and impact resistance are highly relevant to your packaging application. An example which everybody can correspond with is really a garbage bag. I know most have had failure in the garbage bag if it breaks when lifting from the can (tensile strength) or waste elements punctures holes inside (impact resistance). Effortlessly these variables in selecting the right formula to your polyethylene package, developing a knowledgeable salesman is vital.

    Well isn’t there is a great deal to understand making Polyethylene "Film and Bags"!?!
