Manufacturing procedure for supple plastic pack containing loose fibre or granular material is made with two parts joined to form handle at one end

摘要

Plastic pack (2) is made from a plastic film material, either welded or extruded to form a sleeve (4), and has two parts (7a, 7b) that are joined together by transverse weld lines (8a, 8b) to form a handle (5) with an aperture (6). The transverse weld lines are also used to close the pack, which has a preferable volume of over 0.050 m3>, after filling with a bulk fibre or granular material.

The transverse weld lines are also used to close the pack, which has a preferable volume of over 0.050 m3>, after filling with a bulk fibre or granular material. The pack is preferably made from a polyolefin film, but can also be of a combination of paper and plastic as long as it is strong enough to be carried by the handle without the risk of tearing.
