Self-adhesive Kraft Sealing Tape is a widely used encapsulation and fixing material in a variety of industries. It is characterised by its ease of use, strong adhesion and the toughness and durability of the kraft material, which has become an indispensable encapsulation and fixing material in modern society. This article will introduce the production process of self-adhesive kraft paper tape, performance characteristics and application areas.
1. the production process of self-adhesive kraft paper tape
The production process of self-adhesive kraft paper tape is mainly divided into the following steps:
1.1 Kraft paper material selection and processing
Kraft paper material is the main material for the production of self-adhesive kraft paper tape. This material is usually extracted from buffalo or cowhide hides and then processed into rolls for subsequent processing. The kraft paper used to make self-adhesive kraft tapes requires a specific high wet strength kraft paper.
1.2 Preparation of synthetic rubber hot-melt adhesives
Synthetic rubber hot-melt adhesives are the key material for making self-adhesive kraft tapes. It is usually prepared from a series of chemical reactions with petroleum, resins, oxides and other raw materials. The preparation process involves several reactions, distillation and refinement steps, resulting in a hot melt adhesive with good adhesion properties.
1.3 Gluing and drying
To make a self-adhesive kraft tape, hot melt adhesive is applied to one side of the kraft paper and then fixed to the kraft paper by drying and other processes. The hot melt adhesive is usually applied evenly to one side of the kraft paper using a high speed coating machine and then fixed to the kraft paper by a process such as high temperature drying.
1.4 Cutting and packaging
After the hot melt adhesive has dried, the kraft paper needs to be cut to the right size and packaged. Two common packaging methods are rolls and sheets. The rolls are usually used for mass production, while the sheets are more suitable for small-scale production and sales.
2. the performance characteristics of self-adhesive kraft paper tape
2.1 Strong adhesion performance
Self-adhesive kraft paper tape has excellent adhesive properties and can be firmly adhered to a variety of different surfaces. The adhesion force mainly depends on the performance of the hot melt adhesive, hot melt adhesive adhesion performance by the material formula, the viscosity of the hot melt adhesive, the amount of coating and other factors.
2.2 Tough and durable kraft paper
The main material of self-adhesive kraft paper tape is kraft paper, which is tough and durable. With its high tensile strength and abrasion resistance, kraft paper prevents tears and wear. In addition, the natural fibre structure of kraft paper enhances its waterproof and moisture-resistant properties.
2.3 Easy to use
Self-adhesive kraft paper tapes are easy and quick to use and can effectively improve work efficiency. To use, simply cut the tape to the right size and apply it to the desired location.
2.4 High temperature resistance
The hot melt adhesive used in self-adhesive kraft tapes usually has a good resistance to high temperatures and can maintain its adhesion at high temperatures. This property allows self-adhesive kraft tapes to be used for encapsulation and fixing in high temperature environments.
2.5 Good environmental performance
The hot melt adhesive for self-adhesive kraft tapes is usually a synthetic rubber hot melt adhesive, which is environmentally friendly compared to traditional solvent-based adhesives. Hot melt adhesive does not contain any volatile organic compounds, will not cause harm to the environment and health, in line with modern environmental requirements.
3. the application of self-adhesive kraft paper tape
Self-adhesive kraft paper tape is a widely used in a variety of industries, packaging and fixing materials. The main application areas include
3.1 Courier and logistics industry
Self-adhesive kraft tape is widely used in the courier and logistics industry, and can be used for packing cartons, envelopes and bags. Its strong adhesive properties and the toughness of the kraft paper material prevent packages from breaking and loosening.
3.2 Packaging industry
Self-adhesive kraft paper tape has a wide range of applications in the packaging industry. It has good waterproof and moisture resistant properties and can be used to seal and fix various boxes, bags and paper bags.
3.3 Home decoration
Self-adhesive kraft paper tapes can also be used in home decoration. It can be used for fixing and sealing wallpaper, carpets and other materials, which can effectively improve construction efficiency and results.
3.4 Electronic industry
Self-adhesive kraft paper tapes are also widely used in the electronics industry. It can be used for the outer packaging of electronic products, internal fixing and the tying and fixing of wires.
3.5 Automotive industry
Self-adhesive kraft paper tapes have an important application in the automotive industry. It can be used for the fixing of automotive interior parts, wire harnesses, body closure and waterproofing, etc.
4. the purchase and use of self-adhesive kraft paper tape precautions
4.1 Choose the right kraft paper
Self-adhesive kraft paper tape kraft paper material directly affects its use effect, so in the selection should pay attention to the choice of suitable kraft paper. Generally speaking, you should choose kraft paper with high strength and uniform quality.
4.2 Confirmation of adhesion
The adhesive strength of self-adhesive kraft paper tape directly affects its effectiveness, so when choosing a tape, you should pay attention to confirming the adhesive strength. Choose the right adhesive strength for your application to achieve the best possible fixing effect.
4.3 The right way to use
When using self-adhesive kraft paper tape, it is important to pay attention to the correct method of use. The surface to be fixed should be cleaned and dried before use to ensure adhesion and fixing. It is also important to avoid stretching and twisting the tape when using it to avoid compromising its effectiveness.
4.4 Storage conditions
The storage conditions of self-adhesive kraft paper tapes can also affect their effectiveness. Generally speaking, it should be stored in a cool, dry environment, avoiding prolonged exposure to sunlight or high temperatures.
4.5 No direct finger contact with the adhesive layer
The adhesive layer of self-adhesive kraft paper tape is usually made of synthetic rubber hot melt adhesive, which has a high viscosity and adhesion, so care should be taken when using it to avoid direct finger contact with the adhesive layer to avoid affecting its adhesion and use effect.
