White Heat Sealing Pouch Making Paper

Product Description:

Heat sealing paper pouches are made of specialized paper materials that can be sealed using heat. These pouches typically combine paper with a layer of heat-sealable material, such as polyethylene or a similar thermoplastic, to create a durable seal when heat is applied. The paper exterior gives the pouch strength, printability, and a natural appearance, while the internal sealing layer ensures an airtight, tamper-evident, and leak-proof package.

These pouches are highly customizable, with various shapes, sizes, and designs available to suit different products. They are often used for packaging items that require preservation of freshness, such as snacks, coffee, tea, grains, and even non-food products like hardware parts and cosmetics.

Specifications:

• Material Composition:

  • Outer Layer: Typically made from high-quality paper, which could be kraft paper, bleached or unbleached paper, or a paper with a specific texture or finish (e.g., matte or glossy).
  • Inner Layer: A heat-sealable plastic material such as low-density polyethylene (LDPE), biaxially oriented polypropylene (BOPP), or other heat-sensitive polymers.

• Sealing Method: Heat-sealing involves applying controlled heat to the pouch edges, fusing the two materials together to create a tight and secure seal.

• Thickness: Varies based on the product and requirements, but typically ranges from 60 to 120 microns (0.06mm to 0.12mm) for the combined paper and sealing layer.

• Pouch Types:

  • Flat Pouches: Simple rectangular pouches with a bottom fold or side seams.
  • Gusseted Pouches: Expandable sides that allow the pouch to stand upright, providing more storage capacity.
  • Zipper Pouches: Pouches with a resealable zipper to allow multiple uses after the initial seal.
  • Stand-Up Pouches: Pouches with a flat bottom for self-standing, often used for snack foods and other retail products.

• Printing: Heat sealing paper pouches can be custom printed with brand logos, product details, and other graphic designs using flexographic or gravure printing techniques. The paper surface is suitable for high-quality printing.

• Seal Strength: The strength of the seal is determined by the type of plastic used for heat sealing and the temperature/pressure conditions applied during the sealing process. The seal should be strong enough to hold the contents securely and prevent leaks.

• Size Range: Heat sealing paper pouches come in various sizes, ranging from small sachets (e.g., for single-serving products) to larger pouches (e.g., for bulk items). Common sizes might range from 50g to several kilograms in weight.

• Barrier Properties: The paper's outer layer offers some barrier protection against light, while the inner plastic layer provides better protection against moisture, oxygen, and other environmental factors, extending shelf life.

• Eco-friendly Options: Some manufacturers offer biodegradable or recyclable heat-sealing pouches made from paper with environmentally friendly coatings and sealing materials.

• Applications: Ideal for packaging a wide range of products, such as:

  • Food products (snacks, tea, coffee, grains)
  • Non-food items (cosmetics, cleaning products, pharmaceuticals)
  • Industrial items (nuts, bolts, small parts)
