There are both 2-layer (a layer of bubbles is located on a layer of polyethylene) and
3-layer (a layer of bubbles is located inside between two layers of polyethylene) films.
Basic properties:- High depreciation
- Increased mechanical strength
- Impermeability to dust, moisture, dirt
- Good thermal insulation properties, bubbles protect the cargo from sudden temperature changes
- The film is elastic and fits the load well, while having a low weight
- When choosing a film, the main criterion is the density, determined by the amount of material for the production of one square meter of packaging.
