Multi-layer CPP/CPE Self-Adhesive Protective Film

Multi-layer Structure and Functions of Each Layer

CPP Layer (Base Layer)

Serves as a transparent, durable and flexible substrate, providing basic optical and structural performance.

- Highly transparent and glossy, allowing printed information or packaged contents to be clearly visible

- Good flexibility, conforming to and adhering to various surfaces

- Forms the structural basis of the multi-layer film

CPE Layer (Functional Layer)

Enhances durability, chemical resistance and adhesion, complementing the CPP base layer.

- Enhances resistance to environmental factors (such as moisture and abrasion)

- Better chemical resistance than single-layer films

- Improves adhesion characteristics, bonding more firmly to surfaces or other film layers

Key Material Properties

Self-Adhesive Performance

Comes with its own adhesive backing, firmly adhering without the need for additional adhesive, for easy application.

- Firmly adheres to various surfaces (such as paper, plastic and metal)

- Easy to stick and peel, repositionable, suitable for temporary use

- No additional adhesive products required

High transparency and high gloss

Combines excellent optical clarity with a high-gloss surface for enhanced visual appeal.

- High transparency: underlying surfaces or printed content (such as barcodes on labels) remain clearly visible

- High-gloss surface enhances the appearance of labeled/packaged products

Durability and flexibility

The multilayer structure provides mechanical strength, while the material's flexibility makes it suitable for irregular surfaces.

- Tear-resistant and able to withstand various environmental conditions (e.g., handling, storage)

- Remains flexible in harsh environments and conforms to uneven/irregular surfaces without cracking or lifting

Chemical and environmental resistance

The CPP/CPE combination offers excellent resistance to chemicals and environmental stress.

- Chemical resistance: resistant to oil, solvents, and acids

- Environmental resistance: barrier against moisture, UV, and temperature fluctuations

- Stable performance under various indoor/outdoor conditions

Application Scenarios

Labels (Retail/Logistics/Manufacturing)

Suitable for self-adhesive labels requiring transparency, adhesion and durability.

- Applications: product labels, barcode labels, logistics tracking labels

- Performance: remains firmly adhered and clearly legible in harsh environments (e.g., humid warehouses, retail displays)

- High transparency for easy barcode scanning

Packaging (protective wrapping/covering)

For packaging applications requiring transparency, adhesion and product protection.

- Applications: protective wrapping for fragile items, secure covering for packaged products

- Performance: forms a reliable seal to prevent contamination; blocks moisture, dust and other external factors to keep goods intact

Protective cover film (storage/transport)

Used as a temporary protective cover film for surfaces/products during handling, storage or installation.

- Applications: surface protection during transport, dust covering for inventory products, masking during installation

- Performance: dust-proof, scratch-resistant, and protects against minor impact damage; easy to apply and remove, leaving no adhesive residue

Industrial applications (masking/protection)

Suitable for industrial uses that demand durability, resistance, and reliable adhesion.

- Applications: industrial masking (e.g., painting operations), protective film for mechanical parts

- Performance: withstands harsh industrial conditions (e.g., chemical exposure, mechanical stress) and provides long-lasting protection

Eco-Friendly & Safety Features

Recyclability

Recyclable depending on the specific formulation and local waste management regulations, supporting sustainability goals.

- Reduces non-recyclable waste and supports environmentally friendly practices

- Compatibility with recycling systems varies by regional standards and film composition

Safety

The formulation is non-toxic and safe for applications involving direct product contact.

- Meets safety standards for product-contact applications (e.g., retail goods, consumer products)

- No toxic residue or hazardous substances, in compliance with general safety regulations
