BHT Free 63 Micron Film 400Piece Pack

Description

1. Material:

• Polyethylene (PE): This is a widely used and versatile plastic polymer known for its flexibility, water resistance, and relatively low cost.

2. Thickness:

• 63 Microns (µm): This thickness, equivalent to 0.063 millimeters or approximately 0.0025 inches, makes the film durable enough for various protective applications while remaining flexible. It's considered a "thick" film in some contexts, offering good resistance to tears and punctures compared to thinner films.

3. BHT-Free:

• Butylated Hydroxytoluene (BHT): BHT is a synthetic antioxidant sometimes added to plastics, especially in packaging materials, to prevent degradation. However, it has been linked to issues like "phenolic yellowing" in textiles (where the film causes white or pastel fabrics to turn yellow, particularly during storage or transit).

• "BHT-Free" means that this specific film does not contain this additive, making it a preferred choice for applications where phenolic yellowing is a concern, such as in the textile industry for wrapping fabrics and garments. It also makes it a more environmentally conscious option for some packaging needs.

4. Key Properties:

• Moisture Resistance: Provides a good barrier against moisture, protecting enclosed items from humidity and liquids.

• Flexibility: Easily pliable and can be cut, folded, and shaped to conform to various objects.

• Durability: The 63-micron thickness offers good strength and resistance to tearing and punctures.

• Transparency: Typically transparent, allowing visibility of the contents.

• Chemical Resistance: Offers good resistance to many common chemicals, acids, and alkalis.

• Heat Sealable: Can be easily heat-sealed to create secure pouches and bags.

5. Common Applications:

• Textile Industry (Primary Use): This film is most prominently used in the textile and apparel industry, specifically for the Phenolic Yellowing Test (also known as Phenol Yellow Test or Phenotest). It serves as a wrapping material for test samples to assess their susceptibility to yellowing during storage or transit. This is crucial for maintaining the quality and appearance of white and pastel-colored fabrics. It complies with standards like ISO 105-X18, M&S C20B, and NEXT TM43.

• General Packaging: Its properties make it suitable for general packaging where a durable, moisture-resistant, and BHT-free solution is required.

  Protective Covering: Can be used as a protective cover for various items, including industrial equipment, electronics, and other products that need protection from dust, moisture, and light abrasions.

• Medical Applications: May be used for certain sterile packaging or disposable items in the medical field where BHT-free materials are preferred.

In essence, a BHT-Free 63 Micron Film is a specialized polyethylene film designed to provide robust protection and barrier properties, with a key advantage being the absence of BHT, particularly important in preventing yellowing in sensitive materials like textiles.
