HDPE films

Properties of HDPE films

• heat resistant from -50 °C to + 110 °C
• Films are not clear, they are milky-coloured. They have a matt surface, and they are tasteless and odourless and therefore suitable for the direct food contact. Some types are also suitable for use in the pharmacy industry.
• They are resistant to most chemicals, inert to packaged goods.
• They are impermeable to water and little permeable to water vapour, oxygen, fats and aromatic substances (10 x less permeable than LDPE).
• They are very well weldable.

Use of HDPE films

• a semi-finished product for the production of other products (bags, sheets, in-liner in boxes)
• suitable for the production of covering sheets
• suitable for food packaging, especially meat and meat products (more resistant to fat acids)
• a separation layer in the production of bitumen belts (due to their higher heat resistance and minimal shrinkability)

Possible treaments of HDPE films

• full-surface or partial microperforation
• corona treatment for printing or lamination
• printing, colour adjustments
• UV stabilization up to 24 months

Ecology

• HDPE films are environmentally safe and 100% recyclable.
• HDPE films are recoverable in the form of energy recovery and they do not release harmful substances to the environment.
