What is Heat Shrink Film Packaging?
Heat shrink film packaging involves wrapping a product with a plastic film that shrinks tightly when heat is applied. This process creates a secure, tamper-evident seal that protects the product from dust, moisture, and damage. The film is applied using a heat shrink tunnel or a heat gun, which causes the polymer chains to contract and conform to the shape of the product.
Types of Heat Shrink Films
There are several types of heat shrink films, each with unique properties suited for different applications.
1. PVC (Polyvinyl Chloride)
- Characteristics: Low cost, lightweight, and easy to seal.
- Applications: Commonly used for packaging CDs, toys, and non-food items.
- Limitations: Not suitable for food packaging due to potential health risks.
- Characteristics: Food-safe, strong, and highly transparent.
- Applications: Ideal for food packaging, gift baskets, and multi-packs.
- Limitations: Slightly higher cost compared to PVC.
- Characteristics: Durable, puncture-resistant, and suitable for heavy-duty applications.
- Applications: Used for pallet wrapping, beverage cans, and industrial products.
- Limitations: Lower clarity compared to PVC and POF.
4. PETG (Polyethylene Terephthalate Glycol)
- Characteristics: High clarity, excellent shrinkage, and eco-friendly.
- Applications: Suitable for high-end packaging, cosmetics, and premium products.
- Limitations: Higher cost and requires specialized equipment for sealing.
