What is the glue used for packaging tear tape?

The glue used for packaging tear tape is usually a pressure-sensitive adhesive, also known as an adhesive. Pressure-sensitive adhesives are special adhesives that bond quickly after slight pressure is applied, without the need for additional heat, water, or solvents.

Here are some common types of glue used for packaging tear tape:

  1. Acrylic pressure-sensitive adhesive: Acrylic pressure-sensitive adhesive is one of the most commonly used types of glue, it has good adhesion and aging resistance. Acrylic pressure-sensitive adhesive is widely used in packaging tear tape, which can provide a good bonding effect.
  2. Rubber pressure sensitive adhesive: Rubber pressure sensitive adhesive has a high viscosity and adhesion properties, suitable for some packaging tearing tape that needs stronger adhesion.
  3. Silicone pressure-sensitive adhesive: silicone pressure-sensitive adhesive has excellent high-temperature resistance and chemical corrosion resistance, and is used in some special environments, such as high-temperature or chemical contact packaging tear tape.
  4. Hot melt adhesive: Hot melt adhesive is a kind of glue that liquefies at high temperatures and solidifies quickly after cooling, and is also suitable for bonding packaging tear belts.

Adhesive Requirements for Protective Film on Smooth Surfaces

For protective films applied on smooth surfaces, the adhesive requirements are generally relatively low because smooth surfaces have fewer irregularities and are relatively easy for the film to adhere to.

Here are some considerations for adhesive requirements for protective film on smooth surfaces:

  1. Mild Adhesion: Due to the smooth nature of the surface, the protective film only needs to have mild adhesion to ensure it remains in place during transportation and handling, while also being easily removable without leaving residue or adhesive marks upon removal.
  2. Easy Peeling: The protective film on smooth surfaces should have easy peeling properties, making it convenient to remove the film from the surface after use without causing damage or leaving adhesive residues.
  3. No Impact on Appearance: The adhesive requirements for the protective film on smooth surfaces should not be excessively high to avoid leaving marks on the surface or affecting the appearance quality after the film is removed.
  4. Anti-Static: Smooth surfaces are prone to accumulate static electricity, so the protective film needs to have some anti-static properties to prevent static electricity from attracting dust and dirt, thereby keeping the surface clean.
  5. Adaptability: Although smooth surfaces are relatively even, the protective film still needs to have some adaptability to tightly cover the surface and prevent the formation of bubbles and gaps during application.

pressure sensitive adhesive

Overall, protective films on smooth surfaces should have mild adhesion to ensure easy installation and removal, while also requiring good peelability to avoid any adverse effects on the surface of the product. When choosing a protective film, it is essential to match the appropriate film type based on the material and characteristics of the actual product surface to meet the requirements of different application scenarios.
