Heat Sealing Paper Pouch Making Paper

Product Description

Heat sealing paper pouches are made from a combination of paper and a heat-sealable material (often polyethylene or other plastic films). The heat-sealable layer is typically on the inside of the pouch, allowing the pouch to be sealed by applying heat and pressure. These pouches are designed for applications where durability, resistance to moisture, and a strong seal are important. They are commonly used in food packaging, pharmaceuticals, cosmetics, and other industries that require secure, tamper-evident, or moisture-resistant packaging.

Specification:

1. Material Composition:

   • Outer Layer: Kraft paper or other durable, recyclable paper types.
   • Inner Layer: Heat-sealable plastic film, such as low-density polyethylene (LDPE), polypropylene (PP), or polyester (PET).
   • Optional Coating: A barrier layer such as foil, which provides additional protection against moisture, oxygen, and light.

2. Thickness:

   • The thickness of the paper varies between 30 to 120 microns (m), depending on the pouch size and intended use.
   • The thickness of the heat-sealable inner layer typically ranges from 30 to 100 microns.

3. Size:

   • Pouch sizes can range from small (for individual servings) to large (for bulk packaging). Common sizes include:
     • Small (3x5 inches, 4x6 inches)
     • Medium (6x9 inches, 8x10 inches)
     • Large (10x12 inches, 12x15 inches)
   • Custom sizes can be produced upon request.

4. Seal Type:

   • Single Seal: A simple heat seal at the top or sides of the pouch.
   • Double Seal: A more secure method, involving two sealing lines, offering enhanced durability and tamper resistance.
   • Pouch Sealing Options: Easy-tear notches, zipper seals, or perforated edges for easy opening.

5. Sealing Temperature:

   • Typically, the heat-sealing temperature ranges from 120C to 200C, depending on the materials and thickness of the pouch.

6. Strength and Durability:

   • The heat-sealed pouches provide high tensile strength and tear resistance.
   • Suitable for various storage conditions, such as refrigerated, frozen, or room temperature environments.
   • The sealing process ensures that the pouch is resistant to leaks and external elements.

7. Applications:

   • Food Packaging: Snacks, coffee, spices, dried fruits, and other dry food products.
   • Medical Packaging: Sterile items, medical devices, and pharmaceutical products.
   • Cosmetics: Creams, lotions, or other liquid products.
   • Other Uses: Small electronics, hardware components, and various consumer goods.

8. Eco-Friendly Features:

   • Some heat-sealing paper pouches are made with recyclable or biodegradable materials to minimize environmental impact.
   • The paper is often sourced from sustainably managed forests, and some manufacturers offer eco-friendly options that reduce plastic use.

9. Printing and Customization:

   • The outer paper surface can be printed with branding, logos, and product information using flexographic or gravure printing techniques.
   • Pouches can be custom-designed with unique shapes, sizes, and finishes, such as matte or glossy.

Advantages:

• Secure Sealing: The heat-seal provides a tamper-evident and airtight package.
• Moisture Protection: The heat-sealable layer keeps moisture and contaminants out.
• Customizable: Easy to print, size, and design to fit specific needs.
• Cost-Effective: Suitable for medium to large-scale production runs.
• Eco-friendly Options: Some variants are made from recyclable or compostable materials.
