LLDPE

LLDPE and LDPE (low density polyethylene) are widely used in food packaging and are ideal for food storage due to their high resistance to moisture, tearing and chemicals. The graphene-enhanced zipper bags have reportedly shown an increase in tensile strength of 31% compared to non-graphene LLDPE (linear low-density polyethylene) zipper bags. In addition, the increased mechanical strength of the graphene zipper bags allows light weighting of the plastic, reducing the film thickness from 90µm to 60µm per bag.

Driving toward a goal of using more sustainable materials in packaging, two Alexia Organic Potatoes brand products from potato producer Lamb Weston will use corn and potato starch in their packaging beginning in April 2021.

The packaging is partially made of potato starches, a byproduct of producing French fries. Research by GlobalData (March 2021) indicates more than 3 in 10 U.S. consumers believe environmentally friendly packaging material is a key driver of a purchase.
