Quality of Woven Bags for Feed Packaging
Overview
Woven bags used for packaging feed are typically made of polypropylene (PP) particles, which can be a combination of new and recycled materials. The properties of the PP particles greatly influence the characteristics of the PP Bags, particularly their tension and transparency.
New Material Woven Bags
New material pp woven are known for their superior tension and transparency compared to recycled material bags. These pp woven are typically transparent or translucent, appearing white and bright. They exhibit excellent toughness and tensile strength, making them highly durable.
Recycled Material Woven Bags
Recycled pp woven, on the other hand, are evaluated based on the level of material recovery and the amount of masterbatch added. The tension and transparency of these bags vary depending on the proportion of recycled materials used.
Color Classification
The tension and transparency of woven bags can also be categorized by color, although it is not an absolute rule. Generally, for white pp woven, the tension and transparency follow this order: white > yellow > green > gray. However, within the same color category, there are specific rules. For instance:
- Transparent pp woven exhibit higher transparency and tension compared to translucent, bright white, normal white, fog white, and opaque white ones.
- Bright yellow woven bags have better tension and transparency than ordinary yellow and secondary yellow pp woven.
Grammage and Bag Quality
The weight or grammage of woven bags is closely related to their quality. As a general rule, higher weight indicates a thicker bag, implying better quality. This standard applies mainly to grey bags, where the material quality is usually similar and measured by weight.
