In industrial and commercial packaging, the integration of liners into woven bags has proven to be a transformative innovation. Woven Bags with PE Liner offer unmatched protection and versatility, catering to diverse industries such as agriculture, chemicals, and food packaging. This article delves into the characteristics of PE liners in woven bags and evaluates their health and safety standards from an expert perspective.
What Are Woven Bags with PE Liners?
Woven Bags with Liner, often referred to as Woven sacks with Liner or Liner PE Bags, consist of a durable woven polypropylene (PP) exterior and an inner polyethylene (PE) liner. The PE liner is critical for moisture, odor, and contamination protection, making these bags suitable for storing and transporting sensitive materials.
The inclusion of a PE liner enhances the overall bag functionality. Below are some notable advantages of Woven Bags with PE Liner:
- Enhanced Protection: The liner prevents moisture ingress and protects against chemical exposure, ensuring product integrity.
- Versatile Applications: Suitable for storing grains, seeds, fertilizers, chemicals, and fine powders.
- Customization Options: PE liners can be designed as detachable or integrated, tailored to specific industry needs.
Technical Specifications of PE Liners in Woven Bags
The properties of PE liners vary depending on the intended application. The following table outlines the typical parameters of PE liners used in Woven Bags with Liner:
| Parameter | Specification Range |
|---|---|
| Thickness | 20–150 microns |
| Material | Low-Density Polyethylene (LDPE), HDPE |
| Transparency | Transparent or opaque options available |
| Sealing Capability | Heat-sealable for leakproof performance |
| Chemical Resistance | Resistant to acids, alkalis, and solvents |
| Compatibility | Detachable or fixed integration |
These specifications ensure that the bags meet various industrial requirements, providing a reliable solution for diverse applications.
Applications of PE Liners in Aluminum Liner Bags
PE liners are often incorporated into Aluminum Liner Bags, adding an extra layer of protection. These bags are commonly used for high-value or sensitive products that require both thermal insulation and moisture protection, such as pharmaceuticals and food items. The aluminum layer provides barrier properties against light and oxygen, while the PE liner contributes to structural flexibility and additional sealing performance.
