What Is LDPE Heat Shrink Film

Unlike PVC or ordinary polyolefin films, LDPE is fully recyclable and offers superior flexibility, making it especially suitable for irregularly shaped or sharp-edged products. We offer center-fold (C-fold) rolls for high-speed automatic packaging machines, as well as single-wound rolls or roll-in-bag options for manual or semi-automatic lines. All products are treated with anti-blocking agents to ensure smooth machine feeding and reduce downtime.

Key Performance Advantages of LDPE Shrink Film

Feature	Customer Value
Low-temperature shrinkage	Protects heat-sensitive product labels while reducing energy consumption of the shrink tunnel.
High puncture and tear resistance	Effectively resists punctures from sharp edges such as bottle caps and cardboard corners during transportation.
High gloss and clarity	Enhances product shelf appeal, and barcodes can be scanned without removing the film.
Food contact safety	Complies with FDA, EU, and other major market food-grade regulations.
Recyclable LDPE material	Supports sustainable packaging goals and meets environmental compliance requirements.
Anti-block treatment	Prevents film layers from sticking together, ensuring smooth machine operation and minimizing downtime.

FAQ

Q: What is the difference between LDPE heat shrink film and PVC shrink film? How should I choose?

A:The main differences lie in material properties and application scenarios:

Comparison Item	LDPE Heat Shrink Film	PVC Shrink Film
Flexibility	High flexibility with excellent puncture and tear resistance	Stiffer material, prone to brittleness and cracking
Shrink Temperature	Low-temperature shrinkage (approx. 120–150°C), more energy-efficient	High-temperature shrinkage (approx. 160–200°C), higher energy consumption
Environmental Performance	Recyclable, aligned with sustainability trends	Contains chlorine; may release harmful gases when incinerated
Typical Applications	Irregularly shaped products with sharp edges, such as bottled water multipacks, furniture, and electronics	Regularly shaped products, such as DVD cases, trays, etc.

Recommendation: If the products you are packaging are irregularly shaped, have sharp edges, or require eco-friendly packaging, LDPE is a more suitable choice.

Q: Can you customize width, thickness, and roll length? What is the minimum order quantity (MOQ)?

A: Yes. We offer fully customized services:

Size：
Width	100 mm – 2000 mm, slittable to any size
Thickness	20 – 200 microns
Roll length	Customized to your packaging machine requirements
Minimum Order Quantity (MOQ):
Trial orders:	Starting from 500 kg
Regular orders:	Starting from 1 ton
If you need a small batch for testing, please feel free to contact us – we can be flexible.

Q: Can you provide free samples? How do I request one?

A: Yes, we provide free samples for you to test. Simply:
Fill out the inquiry form on this page, indicating "Request free sample" along with the required thickness, width, and other details.
Our customer service team will confirm your shipping address within 24 hours.
The sample is free of charge, but international courier shipping costs are borne by the customer (negotiable depending on order terms).
We recommend testing the sample with your actual products and packaging machine to ensure compatibility.

Q: What type of heat shrink equipment is this film compatible with?

A: Our LDPE heat shrink film is compatible with most heat shrink equipment on the market, including:
Hot air circulation shrink tunnels (most common)
If you are unsure about your equipment parameters, you can provide the shrink tunnel model, heating method, conveyor speed, and other details. Our engineers can then recommend the most suitable thickness and shrink temperature settings.

Q: Can logos or barcodes be printed on the film?

A: Yes. We offer gravure printing services, supporting the following on the film surface:
Brand logos
Product barcodes (EAN, UPC, QR codes, etc.)
Product information and instructions for use
Safety warning labels
Printing supports up to 7 colors and can be customized according to your design files. Orders with printing requirements will involve additional lead time and cost – please specify your needs when requesting a quote.

Q: Is this film recyclable? What are its environmental advantages?

A: Yes, it is recyclable. LDPE (Low-Density Polyethylene) is classified as Plastic #4, a commonly recycled material. Our product:
Uses 100% virgin material or recycled content (based on customer requirements)
Complies with EU plastic taxes and environmental regulations of various countries
Contains no chlorine or heavy metals during production, and emits no harmful gases when incinerated
For companies with clear ESG (Environmental, Social, and Governance) goals, we can provide recycled content certificates and carbon footprint data.

Q: How do you ensure the film does not develop "dog ears" or wrinkles after shrinking?

A: "Dog ears" and wrinkles are typically caused by:
Non-uniform film thickness
Mismatched shrink temperature or conveyor speed
Improper size ratio between film and product
Our solutions:
Use of precision dies and in-line thickness monitoring to keep thickness variation across the entire roll within ±5%
Technical support to recommend optimal shrink parameters based on your product and equipment
Customization of film width and fold size according to your product dimensions for a perfect fit
If you encounter issues during use, we can provide remote or on-site assistance for adjustments.

Q: What is the lead time? What payment methods are accepted?

A: Lead times:
Sample / trial orders: 3–7 days
Regular orders (1–5 tons): 7–15 days
Bulk orders (full container): 15–25 days
Payment methods:
T/T (Telegraphic Transfer): 30% deposit + 70% balance before shipment
For small amounts, Alipay and WeChat Pay are also available (domestic only)

Q: How do you handle quality issues if the received film is defective?

A: We implement strict three-stage quality control:
Every roll undergoes in-line thickness monitoring during production
Random sampling before warehousing – testing shrinkage rate, tensile strength, coefficient of friction, etc.
Final packaging integrity check before shipment
If you find quality issues upon receipt (e.g., excessive thickness deviation, unsatisfactory shrinkage rate, damage, etc.), please provide photos or video evidence within 7 days. We will then, depending on the situation:
Send replacement products that meet specifications
Issue a proportional refund
Arrange technical support for resolution
