Low density polyethylene
(LDPE) is the most versatile choice for a wide range of packaging needs and is the material from which most of our stock poly bags and film
are made. Low density has excellent clarity and the strength to protect most items.
When high clarity is critical to the display of a product,
we can manufacture your film from resin with a low haze.
Linear low density polyethylene
(LLDPE) film has a molecular configuration that is well suited to applications where
strength (puncture strength in particular) is more important than clarity. LLDPE
films tend to stretch more than low density films before breaking, though they are
typically lighter and provide less barrier protection.
its standard LLDPE film from a blend of high-grade resins. However, bags and film
can also be manufactured from pure hexene or octene resin. Hexene is a very strong
LLDPE material that will stand up to more rigorous demands than a standard blend.
Octene delivers the highest performance at a
given weight of any LLDPE material.
Anti-block is an additive that
may reside in polyethylene resin or be mixed with a resin to alter its performance.
When polyethylene resin is extruded, anti-block bleeds to the inside of the bags
and increases the ease with which bags open.
Non-scratch bags and film contain no anti-block additive. Because anti-block additive reduces the tendency of film layers to stick together, non-scratch bags may be more difficult to open.
resin is extruded, slip bleeds to the outside of the bags and increases the degree
to which they slip, or glide. Slip makes bags easy to handle and prevents them from
sticking to one another. High slip bags call for extra slip additive which increases
the degree to which bags glide in any given process or handling, whereas low slip
bags inhibit movement and promote grip.
