Advantages of HDPE Poly Bags
- Better Temperature Resistance:
HDPE has a higher temperature resistance than LDPE or LLDPE, allowing
molded parts to be packed hot off the press, without causing holes or
melt through of the packaging. The softening point of HDPE is
approximately 210-220 degrees Fahrenheit.
- Additive Free:
HDPE is an additive free material. LDPE and LLDPE must have slips
agents and antiblock additives so that the bags do not stick together
(blocking). As HDPE does not contain these additives, it is ideal for
packaging of products that might be adversely affected by contact to
slip and antiblock.
- Non-scratch Properties:
For packaging of optical lenses, HDPE’s inherent additive free nature
is a good choice. The antiblock additive found in LDPE and LLDPE is
typically diatomaceous earth, calcium carbonate or in some cases talc.
All of these additives are abrasives that can cause scratching on
optical surfaces.
- Stiffer, Stronger: HDPE
has a higher density than LDPE or LLDPE resins, making this a stiffer
material. For many applications, this allows the poly bag to be
manufactured thinner, thus saving cost.
- Best Moisture Retension Properties:
Whether the package is trying to hold moisture inside the package, or
keep moisture from migrating into the package, HDPE poly bags are the
best choice.
- Best Low Temperature Resistance:
HDPE poly bags are superior for very cold temperatures, as the
embrittlement temperature is about minus 180 degrees Fahrenheit.

Disadvantages of HDPE Poly Bags
- Clarity:
HDPE is cloudy, almost frosty, when compared to LDPE or PP bags. For
retail applications where the product is being sold outside of the box,
this is not the best choice of materials. For colored merchandise bags,
however, it is a favorite for T-shirt bag style applications.
- Notch Sensitivity:
When HDPE poly bags are notched, they are very easy to tear in the
direction the film was extruded. This can be a disadvantage or an
advantage, depending on the application. In one case, our customer
needed an HDPE poly bag for the moisture retention properties and was
delighted when we showed him how a notch above the seal would allow his
customers to simply "zip" open the package to access the contents.
The
HDPE resins used by Hudson Poly Bag are 100% prime resins, 100% of the
time, never any recycle content. Our HDPE conforms to food contact FDA
regulations under CFR 177.1520(c)(2.2)
