Multi paper sackMulti paper sack

Gusseted polyethylene is inserted into a gusseted kraft paper bag to create a moisture barrier. The bottom of these sacks can be customized based on customer needs with such options as heat sealing or an easy-open process. This original Japanese design can also prevent foreign matter contamination and has better loading efficiency than non-gusseted bags.

Characteristic

1.The interior layer is a polyethylene tube that prevents foreign matter contamination.
2.Due to its gusset, it's loading efficiency is better than non-gusseted bags.
3.Automated production makes these cheaper to produce than manually inserting the polyethylene bags.
4.Micro-perforations (holes < 100 μm) can be added as an option.

Benefits of Micro-perforated Multi Paper Bags (MPMs)

Providing individual solution

When filling paper bags, multi paper bags have better loading efficiency than non-gusseted paper bags. This style of bag is less likely to be damaged during transport. Normally, moisture prevention and perforation features can only be added to non-gusseted paper bags in PE tubes, which lowers the loading efficiency. MPMs allow for moisture prevention and perforations without sacrificing loading efficiency.

Quality Management Method

Siko is the first company to adapt micro-perforation technology to Japan. This is done by using two different quality assurance methods, before and after the process.

Reducing Air Inside Paper After Filling

Micro-perforation is the process of making pinholes (< 100 μm) in the polyethylene layers of our multi paper bags.

This allows air to escape but prevents water from getting inside, creating a kind of ventilation for our MPMs. On a technical level, adding micro-perforations to multi paper bags is quite difficult, but Siko is the only company in the world to successfully commercialize this process.
