Pouch Flexible Packaging Stand-up Color

1. Pouch Flexible Packaging Introduction

Soft bag packaging offers a modern and flexible solution for various products. This soft bag is made of multiple layers of composite materials and has excellent moisture-proof, oxygen-proof and light-proof properties, ensuring that the products maintain their best freshness and extend their shelf life. Its lightweight and space-saving design can reduce transportation costs and environmental impact. There are various styles of soft bags available, including upright, nozzle-equipped and flat soft bags. They can also be equipped with resealable zippers, tearable openings and eye-catching patterns. It is suitable for food, beverages and household products, and the soft bag packaging combines excellent product protection with convenience and high-impact brand promotion, thus being favored by manufacturers and consumers.

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.
