Perforated Shrink Film Engineered for condensation control, hot food packaging, and fresh produce preservation.

Punched shrink film is developed from traditional LDPE shrink film by forming uniformly distributed air-permeable holes on the film surface using precision punching equipment.

1. Excellent Shrink Performance & Secure Sealing

Ensures tight wrapping and stable product bundling during transportation and storage.

2. Breathable Structure for Moisture Control

Allows air circulation and steam release to prevent condensation and fogging.

3. Custom Perforation Design Available

Hole size, density, and spacing can be tailored to meet specific packaging requirements.

4. Wide range of applications

Widely used in food packaging, fresh produce, frozen products, and consumer goods where moisture and visibility control are critical.

Core Advantages of perforated shrink film

1. Precision drilling technology with controllable breathability

We employ high-precision rotary drilling equipment to ensure:

Uniform pore size: Pore size deviation ≤±0.1 mm, stable permeability performance

Precise hole spacing: Customizable hole spacing (20mm-200mm) as required

Punching direction options: single-sided or double-sided punching

Controllable drilling areas: full-width drilling, edge drilling, and spot drilling (holes only in specific areas)

2. Contractility remains unaffected

During heating shrinkage of the shrink film, the perforation regions are prone to become stress concentration points. We employ the following techniques to ensure optimal shrinkage performance:

Reinforcement of perforated areas: No burr or crack on the edge of the hole

Optimization of shrinkage temperature: It is recommended to maintain the shrinkage temperature between 130°C and 150°C to avoid overheating-induced pore edge tearing.

Bidirectional contraction rate equilibrium: After contraction, the majority of pore shapes remain rounded without deformation or enlargement (local edge areas may exhibit slight expansion).

3. Multiple drilling options to suit various scenarios

Depending on different application requirements, the punching methods can be classified as follows:

Punching type	Aperture range	Applicable scene	Characteristic
Micropore	0.5mm-0.8mm	Hot food packaging, baked goods	Discharge hot steam to prevent fogging on the membrane surface
Pinhole	1mm-1.5mm	Frozen foods and refrigerated products	Discharge condensate water to maintain dryness inside the packaging

4. High transparency and brand visibility

Transparency ≥88%: Maintains good transparency after perforation

Does not affect printing: For custom brand printing, the perforation area can avoid printing patterns.

Aesthetics: The micropores are virtually imperceptible and do not affect shelf display performance.

Application of perforated shrink film

Hot food packaging

Applications: Hot dogs, hamburgers, roasted chicken, cooked foods, baked bread
Pain point: Steam accumulation after hot food packaging leads to film surface fogging and packaging bulging.
Solution: Micro-perforation for steam drainage, resulting in compact and aesthetically pleasing packaging.

Frozen foods

Applications: Batteries, electronic components, hardware parts
Pain Points: Moisture accumulation inside packaging may cause product dampness and damage
Solutions: Microporous moisture ventilation to maintain a dry internal packaging environment

Fresh agricultural products

Applications: Vegetables, fruits, flowers, potted plants
Pain point: The product requires ventilation, as ordinary shrink film may lead to hypoxic necrosis.
Solution: Punching and drilling for high-flow ventilation to extend shelf life

Multi-channel logistics services

Applications: Soap, candles, and aromatherapy products
Pain point: The product needs to emit an odor, but conventional shrink film blocks the fragrance.
Solution: Microporous perforation allows odor release while maintaining packaging integrity.

Electronics and Industry

Applications: Batteries, electronic components, hardware parts
Pain Points: Moisture accumulation inside packaging may cause product dampness and damage
Solutions: Microporous moisture ventilation to maintain a dry internal packaging environment

FAQ

Q:Compared To Conventional Shrink Film, Is The Perforated Shrink Film More Prone To Rupture During Shrinkage?

A: No. Our shrink film undergoes specialized processing techniques, with reinforced perforation areas and smooth edges free from burrs or cracks. It is recommended to maintain the shrinkage temperature between 130°C and 150°C (slightly lower than conventional shrink films) to ensure a stable shrinkage process, complete hole integrity, and prevention of edge tearing.

Q: Does Drilling Affect The Transparency And Appearance Of The Shrink Film?

A: Micro-holes (with diameters ≤2mm) are virtually invisible at standard viewing distances and do not compromise product presentation quality. While punch holes (with larger diameters) are visible, they are typically employed in applications such as agricultural products where aesthetic requirements are relatively low. For scenarios requiring both visual appeal and functionality, patterned punching can be selected, with hole positions designed to incorporate brand elements or decorative motifs.

Q: Can Perforated Shrink Film Be Used For Direct Contact Packaging Of Hot Food?

A: Yes. We provide food-grade shrink film made from LDPE raw materials compliant with FDA and EU standards, which can be directly exposed to hot food. The microporous design facilitates rapid steam evacuation, preventing fogging on the film surface and maintaining clear and aesthetically pleasing packaging for hot food. Additionally, the film material itself exhibits excellent thermal resistance, capable of withstanding the temperatures of hot food.

Q: Will The Use Of Perforated Shrink Film For Frozen Foods Lead To Lyophilization Or Air-Drying?

A: No. The needle-punch holes have an extremely small diameter (0.5mm-1.5mm), designed solely to drain condensation caused by temperature differences without significant moisture loss. In practical applications, perforated shrink film effectively prevents water accumulation and freezing within frozen food packaging, thereby enhancing product quality preservation. For products requiring long-term frozen storage, we can customize hole spacing to balance breathability and freshness retention according to your specific needs.

Q: Can Perforated Shrink Film Be Customized For Printing? Will Perforation Damage The Printed Patterns?

A: Customized printing is available. Our perforation technology enables precise control over perforation areas, ensuring the holes are positioned away from printed patterns to fully showcase brand information. Simply provide your design files, and we will plan the perforation locations and spacing based on the printed layout, achieving dual customization for both printing and perforation.
