    Resins… Film thickness… Tensile strength… Impact resistance… So what can most of these terms mean for your requirements when selecting your polyethylene bags?

    If you’re not a poly salesman or have a qualification in Plastics Engineering, the terminology employed in the market probably makes your mind spin. To assist you, we’ve created Polyethylene Packaging 101.

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

    You may find it overwhelming with all the current different resins available today. You can view choose when you’ve got octene, metalocene, butene, hexene, etc… A qualified sales rep are able to help figure out what grade to make use of. Each grade has different characteristics and choices should be based on applications. Understanding resin properties is critical in formulating the correct product on your specific application.

    Film Thickness (Gauge)

    Polyethylene film thickness is measured by thousandths of an inch, or milli-inch. The thickness in the bag doesn’t necessarily correlate into strength. Huge gauge bag may not be strong. Generally this is a blend of resin grade and gauge when compared with the applying. A couple mil octene linear bag will have more strength than a 2 mil butene linear.

    Tensile Strength vs. Impact Resistance

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

    You need to possess a plastic bag that is sufficiently strong enough enough for 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 can be a material’s power to resist shock loading. Precisely what does this implies?

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

    When scouting for the best gauge and resin formula you should consider how tensile strength and impact resistance are tightly related to your packaging application. A good example that can relate with can be a garbage bag. I’m sure they have got had failure within a garbage bag whether or not this breaks when lifting out of the can (tensile strength) or waste material punctures holes inside it (impact resistance). Wonderful these variables in picking the best formula for the polyethylene package, developing a knowledgeable salesman is essential.

    Is not there were much to know about making Polyethylene "Film and Bags"!?!
