Deciding on Packaging Films

2. Deciding on the best flexible plastic
film for your packaging application
can be a complicated process.
There are many variables to
consider in order to best display
and preserve your packaged
product.
Established in 1968 Pyramid
Packaging is a value-added, and
ISO 9001 compliant supplier of
packaging films.

3. Pyramid Packaging can help
you select which of the
following types of films &
variables are required for
your packaging application.

4. Anti-Static
For static sensitive applications – like packaging for electronic
parts or for static sensitive automated packaging or mailing
equipment – anti-static additives lower surface resistivity and
static decay times.
Anti-Block
Blocking is the term used to describe what happens when
polyethylene film sticks together. Anti-block is an additive that
roughens the surface of film at a microscopic level. This makes
it easier for layers of film to separate. Anti-block makes bags
easier to open.

5. High Density Polyethylene
The chemical structure of high density
polyethylene (HDPE) lends itself to
greater toughness – roughly twice the
tear and puncture strength and better
chemical resistance than low density
polyethylene (LDPE) and linear low
density polyethylene (LLDPE). On the
downside, HDPE film is less flexible and
less clear than its LDPE and LLDPE
cousins.

6. Low Density Polyethylene
Low density polyethylene (LDPE) is a popular choice for a wide
range of light-weight packaging needs. LDPE provides
moderate strength and good clarity for general purpose
applications. A commonly used type of LDPE is actually called
Clarity. courtesy of LADDAWN

7. Octene
Octene is the strongest linear low density polyethylene
(LLDPE). For a few pennies more per pound, Octene delivers
the highest tear and puncture strength of any LLDPE material.
Hexene
Hexene is a very strong linear low density polyethylene
(LLDPE) that stands up to more rigorous demands. Hexene is
the most common choice where added strength is important.

Non-Scratch
There’s really only one component in most low or linear low
density polyethylene bags, film or tubing formulations that can
be at all scratchy: anti-block. Anti-block additives work by
making the surface of the film rougher. Non-scratch bags, film
and tubing contain no anti-block additives and therefor provide
smoother film surfaces.

9. Polypropylene
Polypropylene (PP) is the choice when clarity is paramount.
Polypropylene offers about five times the clarity (one-fifth the
haze values) of Clarity low density polyethylene. Polypropylene
is a common choice when packaging for display.

10. Postal Approved
These items are formulated to comply with the USPS T-3204
protocol for use on automation rate flat-size mail pieces.
Performance standards met include haze, blocking, coefficient
of friction and static charge decay.

11. High Slip
Some users require increases in slip additive to increase the degree to which
their bags, film or tubing glide in a handling or packaging process.
Low Slip
Some users require low slip bags, film or tubing to decrease the likelihood of
their product sliding when packaged. Mattress bags are a good example.
Low slip bags are formulated with no slip additive.
Slip
Slip additives decrease the coefficient of friction (increase the slipperiness)
of the surface of a bag, film or tubing. Standard formulations have enough
slip additive.

Direct sunlight (UV light) causes unprotected film to discolor or
become brittle. UVI/UVA (ultraviolet light inhibitor / ultraviolet
light absorber) protects both the film and its contents from the
damaging effects of the sun and inhibits thermal degradation of
the film. Do not use UVI/UVA additive for film that may come in
contact with agricultural chemicals or pesticides as they may
reduce the product’s efficiency.

Packaged metal items can corrode during storage or shipment if
exposed to oxygen, water and other contaminants. A Vapor
Corrosion Inhibitor (VCI) is a film additive that has enough vapor
pressure under normal circumstances to become a gas. VCI fills
the interior of a sealed bag with molecules that adsorb onto the
surface of a metal item to form a microscopic, protective barrier.
