Stretch Film

Stretch Film, also known as stretch film, is a high stretch, self-adhesive, and retractable plastic film that is the core packaging consumable for logistics and warehousing.

Core materials and processes:

1. Mainstream: LLDPE (linear low-density polyethylene), often mixed with LDPE and mLLDPE; Early on, there was PVC; Divided into cast and blow molding processes, the cast film has better transparency and flatness, making it suitable for machine use; Blow molded film has better puncture resistance.

2. Self adhesive: single-sided/double-sided, mostly adhesive between films (without residue), achieved by adding tackifiers or corona treatment.

3. Common specifications: mainly transparent, customizable in black/color; The thickness ranges from 12 μ m to 50 μ m; The stretching rate of the hand film is moderate, and the machine film can reach 300% -500%.

Function and purpose:

Secure the scattered goods on the pallet as a whole to prevent displacement, tipping, dust, moisture, and scratching; No heating required, both manual and machine can quickly wrap. 

Advantages and Attention

1. Low cost: much lower than the combination of cardboard boxes and packing straps; High packaging efficiency and automation capability; PE material is recyclable.

2. Avoid excessive stretching: it will reduce strength and be prone to breakage; The recommended stretching ratios for hand and machine use are different.

At present, the wrapping film is widely used in conjunction with automatic wrapping film Packaging Machines, including door and window packaging, home building materials packaging, advertising board packaging, plastic packaging, electronic product packaging, food packaging, chemical packaging, logistics packaging, etc., greatly improving packaging efficiency and protection effect.
