Introduction

The preservation of food is an essential aspect of reducing waste and ensuring safety. Heat shrink food bags are an innovative solution that have gained popularity due to their effectiveness in maintaining food quality.

Mechanism of Heat Shrink Food Bags

Heat shrink food bags function by tightly enclosing food products within a thermoplastic wrap. This material shrinks when heat is applied, forming a tight seal that reduces the presence of oxygen, a primary contributor to food spoilage.

Materials Used in Heat Shrink Bags

Common materials used include polyolefin and polyvinyl chloride (PVC). Polyolefin is preferred for its non-chlorinated composition and superior clarity, while PVC offers greater durability.

  • Polyolefin: Offers flexibility and clarity.
  • PVC: Known for toughness and resistance to chemicals.

Key Parameters for Optimal Usage

Temperature and time are critical for effective shrinking. Typically, heat shrink bags require a temperature between 90°C and 150°C, with an exposure time of 3 to 12 seconds, depending on the material thickness and desired shrinkage rate.
