Pet Shrink Film

Pet Shrink Film

 

PET shrink film is a high-performance heat-shrinkable packaging film made primarily from PET (polyethylene terephthalate). This product features high clarity, high gloss, and excellent shrinkage properties. It utilizes a center-fold/single-fold structure, making it suitable for automated packaging equipment. When heated, the film conforms uniformly and tightly to the product's shape, creating an aesthetically pleasing, secure, and protective packaging effect. It is widely used for the outer packaging of food, beverages, daily chemicals, pharmaceuticals, and industrial products.

 

PET Shrink Film Features:

1,High clarity:

Crystal-clear appearance provides excellent product visibility and display effect.

Single-piece center-folded design:

The pre-folded structure improves packaging efficiency and reduces operation time.

Uniform Shrinkage Performance:

Shrinks evenly without wrinkles or deformation.

3,Strong and Tear-Resistant:

PET material offers high tensile strength and durability.

Smooth Surface Finish: The glossy texture enhances the overall packaging quality.

 

PET Shrink Film Advantages:

Excellent Display Effect:

1,High-definition transparent film allows for clear visibility of the product, enhancing consumer confidence.

2,High-Strength Protection:

PET material has good toughness, effectively preventing damage from compression, friction, and contamination during transportation and handling.

3,Suitable for Automated Production:

Single-piece folded structure design improves packaging efficiency and reduces labor costs.

4,Stable Heat Resistance:

The shrinking process is controllable, suitable for continuous, high-speed heat shrinking operations.

5,Neat and Attractive Packaging:

After shrinking, the lines are clear and the edges are smooth, enhancing the overall product appearance.

 

PET shrink film product functions:

(Polyethylene Terephthalate)
PET is a common and widely used thermoplastic polyester material, which is very important in the packaging industry (especially in food and printing packaging). The following systematically introduces the characteristics of PET material from the aspects of physical properties, chemical properties, processing performance, and application advantages:

1. Core Characteristics of PET Material

High Transparency and Gloss
High light transmittance, clear visual appearance
Good surface gloss, excellent display effect
Very suitable for high-end food packaging and display packaging
Excellent Mechanical Properties
High strength and rigidity
Good tensile and tear resistance
Strong dimensional stability, not easily deformed
Especially suitable for packaging structures requiring thin yet strong materials (such as PET film, PET shrink film)

2. Good Barrier Properties

Good barrier properties against oxygen (O₂) and carbon dioxide (CO₂)
Moderate moisture resistance (better than PP, weaker than PE)
Conducive to extending food shelf life

3. Excellent Heat and Low-Temperature Resistance

Can withstand high temperatures of approximately 120℃–180℃ (depending on crystallinity and structure)
Not easily brittle at low temperatures
Suitable for hot filling and frozen packaging

4. Good Chemical Stability

Resistant to oils, acids, and alcohols
Stable to most chemicals at room temperature
Does not easily release harmful substances

5. Food Safety and Environmental Attributes

Meets food-grade standards (FDA / EU)
100% recyclable material (RIC #1)
Complies with sustainable packaging trends
