Important things You Have To Be Familiar With Polyethylene Packaging 101
Resins... Film thickness... Tensile strength... Impact resistance... So what can most of these
terms mean to you when selecting your polyethylene bags?
Unless you are a poly
salesman and have a college degree in Plastics Engineering, the terminology found in the
probably makes your mind spin. To work with you, we've created Polyethylene Packaging
Resins (Understood to be: Any one of numerous physically similar polymerized
synthetics or chemically modified natural resins including thermoplastic materials including
polyvinyl, polystyrene, and polyethylene and thermosetting materials like polyesters, epoxies,
and silicones which might be combined with fillers, stabilizers, pigments, as well as other
components in order to create plastics.)
Some think it's overwhelming because of the
different resins available today. Would you choose when you have octene, metalocene, butene,
hexene, etc... A knowledgeable sales representative are able to help know what grade to use.
Each grade has different characteristics and choices ought to be based on applications.
Understanding resin properties is very important in formulating the proper product to your
Film Thickness (Gauge)
Polyethylene film thickness is
measured by thousandths of an inch, or milli-inch. The thickness with the bag does not always
correlate into strength. Much gauge bag isn't necessarily strong. Most often this is a mix of
resin grade and gauge relative to the applying. A couple mil octene linear bag will have more
strength than the usual 2 mil butene linear.
Strength vs. Impact Resistance
Tensile strength will be the maximum stress that the
material can withstand while being stretched or pulled before breaking. Why is this
It is critical to have a very plastic bag which is sufficiently strong 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 is really a material's
ability to resist shock loading. Exactly what does this mean?
Basically it is the film's
ability to resist being punctured. A punctured bag may result in contaminated goods or product
In choosing the proper gauge and resin formula it is important to consider how
tensile strength and impact resistance are highly relevant to your packaging application. An
illustration that everyone can relate to is often a garbage bag. I believe they have had
failure inside a garbage bag if it breaks when lifting from the can (tensile strength) or waste
material punctures holes inside (impact resistance). With all these variables in choosing the
proper formula to your polyethylene package, using a knowledgeable salesman is
Well isn't there was clearly a great deal to understand making Polyethylene
"Film and Bags"!?!
