FAQ
A BACK seal bag (also called a back-sealed pouch ) is a type of flexible packaging where the bag is sealed along three edges (two sides and the bottom), with the back edge formed by folding the film. This design creates a flat, stable base for upright storage and efficient stackingibus leo.
Advantages:
- Enhanced Stability: The flat base allows the bag to stand upright, ideal for retail displays.
- Strong Seals: Multi-layer materials (e.g., PE, aluminum foil) provide tear resistance and protect contents from moisture, oxygen, and contamination.
- Cost-Efficiency: Uses less material compared to four-side seal bags, reducing production costs.
- CustomizabilitySupports branding with printed designs and functional features like resealable zippers
- Dry Foods: Coffee, rice, snacks, spices, and pet food.
- Granules/Powders: Pharmaceuticals, protein supplements, and detergent.
- Liquids/Semi-Liquids: Sauces, honey, and personal care products (e.g., shampoo).
- Industrial Items: Hardware components, screws, and small parts
Materials:
- Base Layers: Polyethylene (PE), polypropylene (PP), or PET for flexibility and durability.
- Barrier Layers: Aluminum foil or metallized films for moisture/oxygen protection.
- Specialty Options: Recyclable PP/RCPP for sustainability or UV-resistant coatings.
Customization:
- Printing: Logos, product info, or barcodes can be added.
- Functional Features: Resealable zippers, tear notches, or anti-static layers.
