If you are looking for the perfect packaging material for your goods and pallets during transportation and logistics, this article will describe the PE and PVC stretch film and compare them for your needs.

 

Here, you will know the different plastic wraps and which packaging projects best suit each product type.

 

PE vs PVC stretch film

PE (Polyethylene) stretch film and PVC (Polyvinyl Chloride) stretch film are both commonly used for packaging and load stabilization, but they differ significantly in terms of material properties, performance, and applications. Here’s a breakdown of the key differences:

 

ストレッチフィルム, also called stretch wrap, is typically made from linear low-density polyethylene (LLDPE). It is an innovative multi-layered process that is used to wrap pallets and secure load stability during transit. LLDPE has good thermoplasticity and transparency. In addition, PE film has extremely strong toughness and can maintain good packaging effects, making it suitable for packaging for long-distance transportation. Moreover, PE stretch film is not easy to shred and is resistant to high temperatures.

 

In terms of environmental protection, polyethylene (PE) has only two elements: hydrocarbon and hydrogen. It is sanitary and non-toxic. PE stretch film is more eco-friendly. For some nations with high export regulations, PE stretch film is a well-known and environmentally beneficial packaging material. The performance is far superior to that of PVC stretch film.

 

PVC stretch films are made from polyvinyl chloride. This type of stretch film relies on the heat resistance of additives, strong toughness, and good ductility. However, because it contains chlorine, it will decompose hydrogen chloride when exposed to sunlight for a long time or above 100℃. In spite, it is also famous due to it is cheap and easy to manufacture.

1. 材料構成

• PE Stretch Film: Made from polyethylene, which is more flexible, lightweight, and cost efficient.
• PVC Stretch Film: Made from polyvinyl chloride, which offers better puncture resistance and more rigid and thicker. Of course, both films provide effective barrier against moisture, dust, dirt, and bacteria.

2. Elasticity & Stretching Ability

• PE Stretch wrap: Known for its excellent stretchability (typically 300-400%) and ability to retain its elasticity even after being stretched. This allows it to tightly wrap around objects, providing strong load retention and stability.
• PVC Stretch Film: Less elastic than PE stretch film, with lower stretchability (usually around 150-200%). This can limit its ability to provide tight wrapping for irregularly shaped loads. PVC film is more resistant to puncture and tears, making it ideal for more delicate items.  

3. Durability and strength

• PE Stretch Film: Stronger and more durable, especially in terms of puncture resistance. It can withstand rough handling and is suitable for heavier loads and palletizing.
• PVC Stretch Film: While it offers good resistance to tearing, it is more brittle and can break under high tension or when used for heavy-duty applications.

4. Clarity and Transparency

• PE Stretch Film: This film has good gloss and looks clear and transparent. Generally, it is ideal for packaging products that need to be displayed or inspected.
• PVC Stretch Film: It also provides good clarity, but it is light yellow in color. And it is prone to discoloration over time, especially under exposure to UV light.

5. 環境への影響

Pe stretch film are more environmentally friendly than PVC films due to PVC can release toxic fumes and then burned. Especially it can release hydrogen chloride which is toxic gas.

6. 料金

PE stretch films are generally more cost-effective for large-scale industrial applications due to their versatility, strength, and lower production cost.

 

結論

In summary, both PVC and PE cling films have distinct advantages and are suited to different applications. PVC cling film offers superior cling, stretchability, and clarity, making it ideal for specific food preservation needs. PE cling film, with its excellent safety profile and recyclability, is a versatile and environmentally friendly option.
