Understanding Gusseted Poly Bags
Gusseted poly bags are constructed from flexible plastic film, typically polyethylene (PE) or polypropylene (PP). A key feature is the gusset, a side seam that creates a wider base. This allows the bag to stand upright, increasing its capacity and making it ideal for displaying products. The gusset improves stability, preventing the bag from collapsing under its own weight. This feature is particularly beneficial for packaging items with irregular shapes.
Technical Features of Gusseted Poly Bags
The technical specifications of gusseted poly bags vary significantly depending on their intended use. Key factors include material thickness (measured in mils), dimensions (width, length, and gusset size), and the presence of additional features. The thickness determines the bag’s strength and durability. Larger dimensions accommodate larger items. Manufacturers offer customizations to meet specific requirements.
