OPF PE EPE Bubble Air Film multi-layer shrink wrap Packaging Machine Solution

1、Brief introduction of the Solution

The system you described—combining an L-type bubble film wrapping machine, an L-type PE film wrapping machine, and a heat shrink tunnel—represents a typical "dual wrapping + heat sealing" composite packaging solution. Below is a concise explanation of its design logic, demand drivers, and target markets.

Design Concept: Modular, Multi-Stage Protection and Appearance Finalization

The core idea of this system is "division of labor and step-by-step reinforcement." The packaging process is divided into three key stages, with each machine performing a specific function:

1. L-Type Bubble Film Wrapping Machine (Inner Layer Protection)

• Function: As the first packaging layer, it automatically wraps cushioning bubble film around the bottom and two sides of the product (typically a carton or regular-shaped item) using the L-type folding method.

• Purpose: To provide protection. The bubble film's elastic cushioning and anti-scratch properties protect the product's edges and surfaces during transportation, preventing scratches, abrasion, and minor impacts. This is the functional core of the packaging.

2. L-Type PE Film Wrapping Machine (Middle Layer Binding)

• Function: As the second packaging layer, it tightly wraps a layer of polyethylene (PE) film around the bubble-wrapped product using the L-type folding method.

• Purpose: To provide bundling and fixation. The PE film’s high tensile strength and elasticity tightly bind the inner bubble film and the product together, preventing the bubble film from loosening or detaching, and forming a preliminary integrated package. This is the stability core of the packaging.

3. Heat Shrink Tunnel (Outer Layer Shaping)

• Function: The PE-wrapped product passes through a tunnel with circulating hot air.

• Purpose: To provide final shaping and aesthetics. The PE film shrinks under heat, conforming tightly to the product’s contour, resulting in a smooth, taut, and visually appealing package. It not only enhances the overall stability of the wrap, preventing the PE film from loosening, but also gives the product a neat, professional shelf-ready appearance, while offering additional dust and moisture resistance.

  
  

Concept Summary:
Bubble film provides "impact resistance," PE film ensures "tight bundling," and heat shrinking delivers "shaping and aesthetics." This modular design allows packagers to flexibly combine machines based on product requirements, offering significantly higher efficiency than manual packaging.
