Basic knowledge of adhesive tape

xinstMar 07, 2020

In daily life, we can see a variety of different tapes, such as warning tapes, electrical tapes, protective film paper adhesive, wrapping film tape, sealing tape, module tape and so on. Each tape application industry is different, and all its characteristics and functions are also different. Today, Ruihua Technology popularizes the basic knowledge of tape, mainly introducing the types, characteristics and applications of ten common tapes in the die-cutting industry.

High Temperature Tape

In the die-cutting industry, the ten most common types of tapes are scotch tape, BOPP sealing tape, fabric-based adhesive tape, foam adhesive tape, kraft tape, masking tape, PVC protective film adhesive tape, and electrical adhesive. Tape, copper foil tape and PET double-sided tape.

First, transparent tape

Scotch tape is made of transparent PET and BOPP film. The two sides are coated with modified acrylic pressure-sensitive adhesive. The white silicone-treated release paper is used as the release paper. It is uniform, transparent and non-hygroscopic, has lasting adhesion, and has good water resistance, steam resistance, UV resistance and aging resistance.

Features: strong adhesion, double-sided adhesion, high strength tensile force.

Application: Used in shoe and leather industry, membrane switch, electronics, circuit board, etc.

Second,BOPP sealing tape

BOPP tape is based on BOPP film and coated with water-based pressure-sensitive adhesive, which has the characteristics of low cost and wide application.

Features: Strong adhesion, large tensile strength, good water resistance and weather resistance, and wide temperature range.

Application: It can be used for packaging of various export outer boxes, with firm performance and certain protection.

Third, cloth-based adhesive tape

Cloth-based adhesive tape is a single-sided adhesive coated with oil-based pressure-sensitive adhesive after being treated with PE resin by a mesh cloth. Easy to tear.

Features: strong adhesion, easy to tear, high fatigue resistance, moisture resistance, and will not cause deformation during shearing.

Uses: Suitable for the packaging of heavy goods. It can be protected by dust, moisture and scratches on the machine. It can be used to protect carpets and telephone lines. It is widely used in industry. It can also be used to strengthen books and folders and prevent slipping. , Printing, silk screen, hardware appliances, etc.

Fourth, foam adhesive tape

Foam tape is made of EVA or PE foam on one or both sides with solvent-based (or hot-melt) pressure-sensitive adhesive and then made of release paper. It has the function of sealing and damping.

Features: excellent sealing, compression deformation resistance, flame resistance, wettability, etc.

Uses: The products are widely used in electronic and electrical products, mechanical parts, various small appliances, mobile phone accessories, industrial instruments, computers and peripheral equipment, auto parts, audio and video equipment, toys, cosmetics, etc.

Five, kraft paper tape

Kraft paper tape is based on kraft paper, coated with pressure-sensitive adhesive, single-sided adhesive, has high strength adhesion, good weather resistance, waterproof, frost-proof, easy to tear, and is an ideal green product.

Features: strong adhesion, high tensile strength, can be torn by hand without deformation, no pollution, and can be recycled.

Application: Paper receiving, carton sealing.

Six, masking tape

Masking tape is a kind of high-quality masking tape. It uses crepe paper as the substrate and is coated with rubber adhesive or hot solvent on one side. It has the characteristics of tight adhesion, easy removal, solvent resistance, and water resistance It is widely used for shielding during surface spraying.

Features: natural color, excellent consistency, strong adhesion, no residual glue when removed, recyclable, smooth cutting of tape edges. The paper is lint-free and unbroken when unrolled.

Application: It is used for laminating, sealing, and color-separating and marking spraying.

Seven, PVC protective film adhesive tape

The PVC protective film is coated on one side by a PVC film substrate. Acrylic or acrylate adhesives have excellent adhesion properties, strong tension resistance, good cold resistance, strong aging resistance, single-sided adhesion, no residual adhesive, and good shielding , Abrasion and solvent resistance.

Application: Suitable for surface protection of various metals, such as aluminum alloy, stainless steel, glass sandblasting.

Eight, electrical tape

Electrical adhesive tape is made of soft polyvinyl chloride film coated on one side with rubber-based pressure-sensitive adhesive. It has good insulation properties, high voltage resistance, high temperature resistance, and high flame retardancy. It is widely used for electrical components and wires. Insulation protection, widely used in electronics and electrical industries.

Features: strong shrinkage elasticity, easy to tear, easy to roll, high voltage resistance, high flame retardancy, good weather resistance.

Uses: It can be used for bandaging electrical wires and air-conditioning pipes, and is widely used for insulation protection in the electrical and electronic industries.

Nine, copper foil tape

Aluminum foil tape is made by applying acrylic pressure-sensitive adhesive on the surface of aluminum foil, sticking on one side, and using silicone-treated release paper. It has good UV resistance, some chemical resistance, moisture resistance, and fire resistance. It is mainly used in refrigeration and electronics related industries.

Features: bright silver, UV resistance, fire resistance, can prevent more chemical corrosion, outdoor applications, good weather resistance.

Uses: Can be used for hot and cold reflective insulation and heat insulation, can be used in pipes, engine supports, can be wrapped in wires to prevent heat, waterproof and dustproof, etc., can also be used for outdoor work.

Ten, PET double-sided tape

PET double-sided tape is made of PET double-coated acrylic adhesive. The color of the tape is generally transparent and black. The common thickness specification is 0.03-0.25MM, which has good dimensional stability, thermal stability and chemical stability. , Good initial viscosity and stickiness, easy to die-cut processing, good adhesion to plastic, rubber, nameplate; can be used in a wider temperature range and harsh environment; long-term temperature resistance 100-120 ℃.

Features: Good adhesion to the substrate; high bonding strength to high surfaces such as plastic and metal foil; excellent temperature, water and chemical resistance.

Uses: It is suitable for the isolation and bonding of the upper and lower lines of the membrane switch. The high-performance adhesive exhibits extremely high stability and is suitable for the long-term use requirements of the keys.
