Multiwall sacks are mostly used for packaging industry and chemical raw materials, while single-layer bags are mostly smaller handbags and are mostly used for packaging clothes and gifts etc. Single-layer paper sacks are very common in daily life, while multiwall paper sacks are rarely seen. Many people don’t understand this kind of packaging. Let’s take Baijia industrial paper bag factory as an example to introduce the types of multiwall paper sacks.
With the gradual deepening of social awareness of environmental protection, plastic bags packaging are gradually being banned by many countries due to their unfriendly nature.

Enhanced transportation safety, less breakage and waste.
