HDPE bag stands for High Density Polyethylene – the type of particles that make up HDPE bags. HDPE bags are also known as foam bags or HD bags. In other words, HDPE bags are PE bags but in a special, more advanced form because they are made from high density PE plastic.

In addition, HDPE bags are also called foam bags because they have poor flexibility, fold easily, wrinkle easily, and when rubbed, they easily create loud rustling noises.

Characteristics of HDPE bags

HDPE bags have similar characteristics to LDPE bags, because these two types of bags are both produced from Polyethylene material, the only difference is that HDPE is polymerized from Polyethylene (with high density) at relatively low pressure with catalytic systems such as Catalyst, Chromium/Silic. Some basic characteristics of HDPE bags include:

  1. Low production costs
  2. Light weight, chemical resistant
  3. The surface is highly glossy and transparent
  4. Safe, non-toxic
  5. High surface smoothness
  6. High water resistance but poor air permeability

  4. Laundry bag
  5. Garment industry packaging
