In the era of pursuing sustainable development and environmentally friendly packaging, Kraft paper tape stands out with its unique advantages and has become the first choice for packaging and sealing in many industries.
Kraft paper tape is a tape made of high-strength kraft paper as the base material and coated with a special adhesive (commonly water-activated adhesive or hot melt adhesive). The core lies in the natural, renewable, and recyclable characteristics of the kraft paper base material, making it an environmentally friendly solution to replace traditional plastic tapes.
Advantages of Kraft Paper Tape
Excellent environmental protection
Recyclable & biodegradable: The kraft paper base material is made from wood fiber, which is easy to recycle and process. Additionally, natural kraft paper is biodegradable under certain conditions, significantly reducing plastic pollution and white waste.
Renewable resources: The main raw materials come from well-managed forest resources (often with FSC/PEFC certification), which are in line with the concept of sustainable development.
No plasticization: It does not contain plastic components (such as PP, PVC), and no harmful gases are released during incineration, meeting the increasingly stringent environmental regulations.
High strength and durability:
High-quality kraft paper has excellent tensile strength and tear resistance, and can firmly seal various heavy and special-shaped cartons. It is especially suitable for scenarios with high packaging strength requirements, such as e-commerce, logistics, and manufacturing.
Good weather resistance: It has a certain tolerance to temperature changes and ultraviolet rays (UV), and is not easily aged and becomes brittle.
Excellent adhesion:
Water-activated glue (water kraft paper tape): It activates viscosity when it comes into contact with water, forming a "fiber hinge" with the surface fibers of the corrugated box. It has extremely strong adhesion and is almost "part of the carton", providing permanent sealing and a good anti-tampering effect.
Hot melt adhesive type (self-adhesive kraft paper tape): It can be peeled and pasted, is easy to use, has strong adhesion, is suitable for dry environments, and rapid sealing needs.
Good printing suitability:
The surface roughness of kraft paper is moderate, which makes it easy to print with high quality (such as corporate logos, environmental protection logos, warnings, etc.), enhancing brand image and product recognition.
Beautiful and simple:
The natural kraft paper's original color or printing effect conveys an environmentally friendly, natural, and reliable brand image, which is favored by brands that focus on corporate social responsibility (CSR) and consumer experience.
Main types of Kraft paper tapes
Classification by adhesive:
Water kraft paper tape: Glue needs to be applied/activated by a water device, with the strongest adhesion and usually low cost, making it the first choice for heavy packaging.
Self-adhesive kraft paper tape (hot melt adhesive/pressure sensitive adhesive): Self-adhesive, ready to use, easy to operate, suitable for automatic or manual fast sealing.
Double-sided kraft paper tape: Glued on both sides, mainly used for special lamination, fixation, or handicrafts.
Classification by substrate color/treatment:
Original Kraft paper tape (natural yellow-brown)
Bleached kraft paper tape (white)
Coated/laminated kraft paper tape (enhanced waterproof, moisture-proof, or printing effect)
Classification by reinforcement method:
Ordinary Kraft paper tape
Fiber-reinforced kraft paper tape: Glass fiber or polyester fiber filaments are embedded in the substrate to greatly improve the tear strength and are used for sealing overweight boxes or high-value items.
Core application industries of Kraft paper tape
E-commerce and logistics: It meets the needs of high-strength sealing, brand display, and environmentally friendly image, and is an environmentally friendly packaging material recommended/required by e-commerce platforms.
Food and beverage industry: It meets food contact safety requirements and is used for sealing food cartons.
Medicine and cosmetics: The image of environmental protection and safety fits the industry tone and is used for product outer packaging.
Manufacturing and industry: Packaging and sealing of industrial products such as heavy equipment and parts.
Home and furniture: Sealing of large and heavy cartons.
Postal express service: Provide reliable packaging.
Eco-friendly and organic products: As part of the overall eco-friendly packaging strategy, convey brand values.
Kraft Paper Tape Use and Storage Tips
Wet Water Tape: Make sure to apply enough water evenly; avoid applying too much water to make the paper too soft; apply pressure for a few seconds after sealing for better results; unused tape needs to be sealed to prevent moisture.
Self-adhesive Tape: Make sure the pasting surface is clean, dry, and free of oil; paste and apply pressure as soon as possible after tearing off; store in a cool and dry place to avoid high temperature and humidity that affect stickiness.
General: Avoid storing unused tape for a long time in extreme cold (which may cause the glue to become brittle) or high temperature and high humidity.
