Heat Sealing Paper

Heat sealing paper is commonly used in packaging applications, particularly for sealing and closing plastic bags or pouches. The paper is designed to be heat-sealed to a plastic film to provide an airtight and secure seal. It is often used in the food, pharmaceutical, and medical industries, as well as in other consumer goods packaging.

Description of Heat Sealing Paper: B12

Heat sealing paper is typically a special type of coated paper, often laminated or treated with a heat-sensitive layer that activates under heat. This allows it to bond tightly with certain plastic materials, providing a strong seal. Heat sealing paper is available in different grades, thicknesses, and finishes, depending on the application and type of plastic to be sealed.

Key Features:

• Heat Sensitivity: The paper is coated with a layer that activates when exposed to heat, making it easy to bond with plastic films.
• Moisture Resistance: Some heat sealing papers are specially treated to resist moisture, enhancing their durability and reliability in sealing applications.
• Compatibility: It is compatible with various types of plastics such as polyethylene (PE), polypropylene (PP), and other thermoplastic materials.
• Variety of Applications: Heat sealing paper can be used for sealing food packaging, medical products, and consumer goods.

Specifications:

The specifications for heat sealing paper vary depending on the manufacturer and intended use. However, here are some general specifications you may find:

• Material: Typically made from paperboard, kraft paper, or other paper substrates that are coated with a heat-sealable layer (e.g., polyethylene, EVA (ethylene-vinyl acetate)).
• Thickness: Ranges from 50gsm (grams per square meter) to 250gsm or more, depending on the strength required for the seal.
• Coating: The paper may be coated with a heat-sealing layer such as PE or EVA, which ensures strong adhesion to the plastic material.
• Heat Sealing Temperature: The sealing temperature generally ranges from 120°C to 180°C, depending on the coating and the materials being sealed.
• Adhesion Strength: The paper provides a strong adhesive bond with plastic films, creating a reliable and airtight seal.
• Moisture Barrier: Some types of heat-sealing paper are treated for added moisture resistance, making them suitable for food and medical packaging.
• Color: It can be produced in various colors, including natural kraft brown, white, or custom colors based on branding requirements.
• Roll or Sheet Format: Available in rolls or sheets, with custom lengths and widths depending on the manufacturer or the packaging machinery being used.
• Tensile Strength: Tensile strength can range from 10 to 30 N, depending on paper grade and thickness.

Applications:

• Food Packaging: Used to seal food pouches and bags, such as snacks, dry foods, and frozen items.
• Pharmaceutical and Medical: Used for sealing medical supplies, such as sterile packaging for bandages, syringes, and other medical products.
• Consumer Goods: Applied in packaging various consumer items that require airtight and tamper-proof seals.

Advantages:

• Strong Seals: Provides an effective, durable seal for packaging.
• Customizable: Available in various coatings, thicknesses, and finishes to meet specific requirements.
• Environmental Considerations: Some heat-sealing papers are designed to be recyclable or biodegradable, making them suitable for environmentally-conscious packaging solutions.
