1. High strength and durability: Lay flat poly bags are made of 100% virgin LDPE with a tensile strength of over 15 MPa, providing excellent tear resistance even under heavy loads. The 3.6C thickness ensures reliable performance during, stacking, or transportation.

   
   

2. Transparent and smooth: Each bag has a high optical transparency level with light transmittance over 92%, ensuring clear visibility of contents for easy identification. The flat and smooth surface design also improves labeling accuracy and minimizes wrinkling. 

   
   

3. Multiple colors available: Lay flat poly bags are available in multiple color variations, including transparent, blue, pink, purple, and yellow. The pigments are blended with UV stabilizers to maintain color consistency and prevent discoloration under long-term storage. 

   
   

4. Environmentally friendly and odorless: Manufactured using food-grade LDPE, these bags are free from heavy metals and plasticizers. The volatile organic compound (VOC) emission is below 50 mg/m², ensuring no odor or contamination during garment or fabric storage. 

   
   

5. Precision sizing: The production tolerance is controlled within ±3 mm for length and width, ensuring compatibility with automated cutting and sealing machines. Standard dimensions include 740×1120mm, and thicknesses can be customized between 2.5C and 5C based on application requirements. 

1. Garment Manufacturing: Lay flat poly bags are widely used in garment factories for storing and protecting cut fabric pieces before sewing. Their anti-dust and smooth characteristics prevent lint accumulation, ensuring fabric cleanliness. According to user reports, productivity in sorting processes can increase by 18% when these bags are used in the cutting section.

   
   

2. Textile Packaging: In textile mills, these bags are used for packing woven or knitted fabric samples. The strong sealing ability protects materials from moisture absorption and contamination. When used in warehouses with high humidity, they can maintain fabric quality stability for over six months.

   
   

3. Industrial Parts: These bags serve as a reliable dust-proof solution for metal and plastic components. LDPE’s low surface resistivity (10¹¹ Ω cm) helps prevent static buildup, which can otherwise attract fine particles or cause surface scratches on sensitive materials.

   
   

4. Electronic Products: For electronics assembly lines, lay flat poly bags can store cables, sensors, and connectors. Their anti-static and transparent nature facilitates fast visual checks without compromising component protection. The use of 3.6C material ensures a balanced performance between flexibility and barrier strength.

   
   

5. Daily Necessities Packaging: The bags are also suitable for packaging stationery, accessories, or soft goods. Their printable surface supports logo customization, helping brand visibility. Combined with the option of tinted finishes, these bags present both practicality and aesthetic appeal in retail applications.

1. What material are lay flat poly bags made of?

They are made from 100% low-density polyethylene (LDPE), which offers flexibility, durability, and excellent clarity. The material is recyclable and compliant with environmental standards such as REACH and RoHS.

2. Can the size and thickness be customized?

Yes, the bags can be customized from 2.5C to 5C in thickness and in multiple size ranges. Common large sizes include 740×1120mm and 900×1300mm, depending on your packaging requirements.

3. Are these bags suitable for food contact?

The standard lay flat poly bags are industrial-grade, but food-grade versions can be produced upon request using certified materials that meet FDA standards.

4. Do the bags support printing or labeling?

Yes, the surface supports ink printing, logo marking, and warning text. Printing adhesion is tested with a peel strength greater than 1.2 N/cm, ensuring long-lasting clarity and durability.

5. How should the bags be stored to maintain quality?

Keep them in a cool, dry place below 30°C and away from direct sunlight. Under these conditions, lay flat poly bags retain their physical properties and transparency for up to two years.
