pinch bottom bag / coated fabric / polypropylene

1st pinch bottom bag worldwide made fully automatically from PP fabric

The PP*STAR® concept unites the best qualities of woven polypropylene tape fabric and printed BOPP film to create a cutting-edge packaging material for dry bulk goods sold in the retail sector. Designed as pinch bottom bags, PP*STAR® bags are perfectly suited for packaging dry pet food or fertilizer, but also meet the requirements of other products such as seeds, flour, sugar, or rice.

Light, strong, attractive, eco-friendly

The trend in packaging materials goes towards reducing their weight – less weight means less input material.
The result: lower raw material costs and a positive environmental impact.

The challenge in reducing the weight of a packaging material is to maintain its important properties such as tensile strength and tear resistance, while at the same time the material layer becomes thinner and lighter. In applications where bulk goods are packaged in bigger quantities, and especially if these goods need adequate protection against environmental influences or breakage, there has been no way around multiwall paper bags or thick plastic sacks.

Until now.
A composite of BOPP-laminated polypropylene tape fabric like PP*STAR® is strong enough to carry high quantities of content, making multiple-layer packaging no longer a necessity. An average single-layer PP*STAR® bag that holds 25 kg of content weighs only 118 g – a weight reduction of more than 55 % compared to a 4-ply paper sack of the same size.
