Transparent Flexible Packaging Stand-up Pouch

1. Transparent Flexible Packaging Introduction

This product is refined from high-strength transparent composite plastic film and meets diverse packaging needs with its excellent practical performance. The packaging bag is crystal clear throughout, perfectly displaying the original appearance of the contents, and has excellent waterproof, moisture-proof, and tear resistant strength, providing intimate and reliable protection for the product. Its material is lightweight and flexible, with a firm seal, significantly improving the convenience and safety of storage and transportation. Whether used for food, daily chemical products, or daily necessities, it can effectively enhance product image with high cost-effectiveness and clear display effect, making it an ideal choice for modern commercial packaging.

3. Flexible Packaging Features

Material: Composite of single or multiple plastic films (such as BOPP, CPP, PE, PET, PA, EVOH).
Appearance: From fully transparent to any color, with high glossiness, it can present the product itself and has strong visual appeal.
Texture: Soft, smooth, good toughness, excellent tear and puncture resistance.
Barrier properties: Various barrier requirements can be achieved from low to high through the combination of different materials, with flexible design.
Structure: It is mostly a multi-layer co extruded film or composite film, such as BOPP/CPP, PET/PE, BOPA/EVOH/PE.

4. Flexible Packaging Theory

Protection principle: Based on the inherent barrier properties of different polymer materials. By designing a multi-layer structure, each layer can play a different role:
Outer layer: Provides printability, wear resistance, and strength (such as BOPP, PET).
Intermediate layer: Provides high barrier properties (oxygen and fragrance resistance), such as EVOH, PA, and aluminum foil.
Inner layer: Provides thermal sealing and chemical resistance (in contact with the contents), such as PE and CPP.
Mechanics principle: By utilizing the toughness and ductility of plastic materials, they can restore their original state through external forces or absorb energy through deformation, thereby resisting external impacts and punctures.
