Product Overview
The transparent OPP square bottom bag with gusset is a lightweight, high-clarity flexible packaging solution designed for candy, popcorn, snacks, and retail products. It features a square bottom that allows the bag to stand upright for display, while the side gussets expand to provide extra capacity. Made from food-grade OPP (oriented polypropylene) film, it offers excellent transparency, moisture resistance, and printability. The bag can be heat-sealed and is suitable for manual or automated filling.
Laminate Structure
The product is typically made from a single layer of food-grade OPP film, or a composite structure such as OPP/CPP for enhanced heat-sealing strength. Common specifications:
- Standard: Single-layer OPP, 25–40 microns.
- Composite option: OPP/CPP, 30–50 microns, for better seal integrity and stiffness.
- Surface: Glossy or matte finish available.
- Food contact: Inner layer complies with food-grade safety standards.
Key Features
- High clarity: Excellent transparency for product visibility and shelf appeal.
- Self-standing: Square bottom design keeps the bag upright without external support.
- Expandable gussets: Side gussets increase capacity and allow flexible filling.
- Moisture resistant: OPP film provides good moisture barrier to keep contents fresh.
- Heat-sealable: Can be sealed with standard impulse or constant heat sealers.
- Lightweight: Reduces shipping costs and material usage.
- Printable: Supports up to 8-color gravure printing for branding and promotional graphics.
