Plastic Flexible Packaging Resealable Closure

1. Plastic Flexible Packaging Introduction

This new green composite plastic packaging bag features a refreshing color tone full of vitality and natural atmosphere as its visual highlight, designed specifically for products that pursue a healthy and natural brand image. The packaging bag adopts multi-layer composite technology, which ensures excellent sealing, moisture resistance, and durability. At the same time, its soft green texture can effectively highlight the fresh characteristics of the contents (such as food, tea, cosmetics, etc.), instantly conveying brand information of environmental protection, safety, and vitality. It not only provides reliable physical protection, but also becomes an efficient visual communication medium, helping your product stand out on the shelf and attract consumers' favor.

3. Flexible Packaging Advantages

Excellent barrier and protective properties: The required water vapor, oxygen, and ultraviolet barrier properties can be precisely designed through material combinations, providing a longer product shelf life.
Lightweight and Soft: Extremely lightweight, can greatly reduce transportation costs and carbon emissions; Soft and easily deformable, it can reduce the space occupied by content.
High strength and durability: Excellent impact resistance, puncture resistance, and tear resistance, which can better protect the contents.
High transparency and glossiness: Fully transparent or glossy surfaces can perfectly display products and stimulate purchasing desire.
Functional diversity: Easy to implement multiple functions such as resealing zippers, suction nozzles, anti-counterfeiting openings, microwave heating, steaming, etc.

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.
