Advantages of PELD
Evaluation table for materials
By a direct comparison between the three most used materials for baskets, the following table of advantages/disadvantages appears on an objective basis :
PP = Polypropylene. Recycling label (05).
PEHD = Polyethylene High Density. Recycling label (02).
PELD = Polyethylene Low Density. Recycling label (04).
+ + = highly qualified
+ = qualified
– = unsuitable/less suitable

PEHD can cause stress release by contact with ordinary brown soap.
Stress relief unfortunately means cracks or that the basket splits.
PEHD is in constitutive form not suitable to UV-light.
Can have UV stabilizer added, but will then not be suitable for food contact to animals and human beings.
When PEHD and PP split, sharp edges will appear which people can cut themselves on.
