The future of green packaging: kraft paper tape

There are various types of kraft paper tape, which can be categorized into two major types based on the adhesive coating on the substrate: water-free kraft paper tape (self-adhesive) and water-activated kraft paper tape (re-moistenable).

Self-adhesive kraft paper tape, also known as water-free kraft paper tape, is made of coated kraft paper as the base material and coated with glue. Depending on the glue applied, self-adhesive kraft paper tape can be subdivided into hot melt adhesive type and water glue type, oil type, rubber type, etc. It can be printed and screened as required. It has the advantages of waterproof, strong adhesion, high tensile strength, good retention, no edge warping, and stable weather resistance.

Water-activated kraft paper tape, also known as re-wet kraft paper tape, is made of kraft paper substrate and coated with edible plant starch adhesive. It becomes sticky after being soaked in water. It is environmentally friendly, pollution-free, recyclable and recyclable, and is anti-unboxing. The high viscosity does not cause warping and has a long shelf life, ensuring that the viscosity remains effective for a long time without getting wet. It must be wetted with water to produce stickiness, and it has the characteristics of being able to write on kraft paper. It is suitable for sealing export cartons or covering carton writing, and can also be used for printing.

Invention of Kraft Paper

The official English spelling of kraft paper tape is "Kraft Sealing Tape." Historically, kraft paper was indeed made from the hides of cows. However, due to the high cost and the advancement of human understanding of chemical synthesis, wood fibers are now used to synthesize kraft paper, which, after special chemical treatment, resembles cowhide in appearance and texture.

Because of the use of wood fiber, this paper has high tensile strength and tear resistance, making it ideal for securing heavy packages, particularly for sealing heavy-duty cartons. Since it is opaque, it is also commonly used to cover markings on the surface of objects.

Characteristics of Kraft Paper Tape

With its waterproof, oil-proof, and anti-corrosion properties, kraft paper tape is mainly used in industry. For example, carton sealing and packaging, carton printing shielding, clothing surface treatment, packaging of heavy objects, etc.

1.High Strength: One of the main features of kraft paper tape is its high strength. Due to the inherent high strength and burst resistance of kraft paper, kraft paper tape has correspondingly high tensile strength and burst resistance, meeting various usage requirements.

2.Durability: Kraft paper tape also has excellent durability, maintaining good performance even in humid environments. This durability allows it to perform well in outdoor settings and moist conditions.

3.Environmental Friendliness: Another significant feature of kraft paper tape is its eco-friendliness. Made from natural kraft paper and eco-friendly adhesive, it can quickly degrade in natural environments without causing pollution. In the context of global sustainability, kraft paper tape, as an eco-friendly material, has gained increasing popularity.

Applications of Kraft Paper Tape

Kraft paper tape has a wide range of applications, mainly reflected in the following aspects:

1.Packaging and Securing: Kraft paper tape is used for packaging and securing items like cartons, gift boxes, and fabrics, increasing the stability of the packaging and preventing movement or damage during transportation. It is also commonly used in logistics and transportation for sealing cartons and securing goods, ensuring the safety of items during long-distance transport.

2.Bonding and Repairing: Kraft paper tape can be used for bonding and repairing various materials, such as plastic, glass, and metal. Its strong adhesive power allows damaged or broken items to quickly regain their original functionality.

3.Decoration and Interior Design: Kraft paper tape is widely used in decoration and interior design, such as in offices, homes, and hotels. It can be used for edge banding of furniture, seam covering, veneer bonding, and weaving edges. Using kraft paper tape can enhance the texture and aesthetics of decorations while protecting surfaces from damage.

4.Labeling and Identification: Kraft paper tape can be used to create various labels and stickers for identifying documents, materials, products, and more. Its durability and waterproof properties ensure clear and lasting markings, helping to improve work efficiency and reduce errors.

Kraft paper tape not only offers practicality but also high environmental value compared to traditional plastic tapes. As global awareness of environmental protection increases, kraft paper tape, as an eco-friendly, biodegradable material, supports the industry's move toward greener, low-carbon development. Its applications continue to expand, providing strong support for the growth of various sectors.
