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).
Grading:
+ + = highly qualified
+ = qualified
– = unsuitable/less suitable

Note 1
PEHD can cause stress release by contact with ordinary brown soap.
Stress relief unfortunately means cracks or that the basket splits.
Note 2
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.
Note 3
When PEHD and PP split, sharp edges will appear which people can cut themselves on.
