PE Bags

Polyethylene (PE) is the standard material for bags in the packaging industry. This versatile plastic is particularly valued as a sealing medium on the inside. For the outside of a PE bag, however, there are a number of options. Bags with an MDO-PE exterior are PE mono-material structures designed for recycling, whereas composites with a PET exterior are not mono-materials and are currently difficult to recycle. However, this variant offers numerous advantages in further processing.

HDPE, LDPE and MDO-PE – the differences explained

Not all PE is the same. In fact, this special packaging and film plastic comes in a variety of material qualities. These different PE variants make it possible to tailor packaging precisely to specific requirements – from simple e-commerce packaging to demanding applications in the food industry.

While HDPE (high-density polyethylene) is primarily used for robust and resistant packaging, LDPE (low-density polyethylene) is the first choice for soft, malleable bags that impress with their high flexibility and transparency. In comparison, LLDPE (linear low-density polyethylene) offers improved mechanical properties such as increased tensile strength and puncture resistance, which increases the durability of PE bags made from LLDPE. MDO-PE (machine-direction oriented polyethylene) is a PE film that has been stretched in the machine direction, which gives it higher stiffness, better printability and improved transparency. This allows it to replace PET as the outer film, so that the entire bag can be produced as a PE mono-material structure designed for recycling.

PE bags are considered true all-rounders in the packaging industry. While they are used in the food industry to package loose goods ranging from fine tea to premium spice blends, the cosmetics and pharmaceutical industries use these versatile bags to package medicines, care products and medical cannabis. For liquid products such as lotions or oils, PE stand up pouches are used, which are sealed watertight and equipped with integrated openings or sealable valves. Samples produced for marketing purposes can be packaged perfectly in the smallest versions of PE bags. PE bags also play an important role in B2B trade as partially standardised packaging for small parts and components of all kinds.
