What is Double Sided Tape?
Double-sided tape is any pressure-sensitive tape that is coated with adhesive on both sides.[1] It is designed to stick two surfaces together, often in a way which is not visible in the end product, due to it being in between the objects rather than overlaying them.
This allows for neater-looking projects and better craftsmanship. Double-sided tape can be either thin or dimensional. Dimensional tape is thicker, and is of particular use to retail and signage uses where it can be used to allow signs or displays to stand out with a 3-D effect.
Double-sided tape is created by applying a thin adhesive layer to each side of a carrier material. For example, double-sided tissue tape, an easy-to-rip double-sided tape,
is created by applying adhesive to two sides of tissue paper, which is then wound with a silicone paper to avoid it sticking to itself. Most adhesive tapes are manufactured in log form,
such as a large 1 to 3 meter wide roll, and then an adhesive tape converter is used to slit the rolls into the required widths.
One type of double-sided tape, known as lingerie tape, secures clothing to skin, and is used with strapless dresses or loose skirts, and as a temporary fix for fallen hems and other clothing imperfections.
Types of Double Sided Tape?
1. PET Double-sided tape : good temperature resistance and strong shear resistance, generally long-term temperature resistance 100-125 °C, short-term temperature resistance 150-200 °C, thickness is generally 0.048-0.2MM, suitable for nameplate, Bonding of LCD, decorations and decorative parts.
2. Non-woven double-sided tape( tissue paper double sided tape) : good viscosity and processability, generally long-term temperature resistance of 70-80 °C, short-term temperature resistance of 100-120 °C, thickness is generally 0.08-0.15MM, suitable for nameplate, plastic Lamination, automotive, mobile phone, electrical appliances, sponge, rubber, signage, paper products, toys and other industries, home appliance and electronic instrument parts assembly, display lens.
3. Double-sided adhesive without substrate: It has excellent adhesion effect, can prevent falling off and excellent waterproof performance, good processability, good temperature resistance, short-term temperature resistance of 204-230 °C, and general long-term temperature resistance of 120-145 °C , the thickness is generally 0.05-0.13MM, suitable for the bonding of nameplates, panels and decorative parts.
4. Foam double-sided tape: refers to a kind of double-sided tape formed by applying strong acrylic adhesive on both sides of the foamed foam substrate, and then covering one side with release paper or release film. Forming paper or release film is called sandwich double-sided tape, and sandwich double-sided tape is mainly used to facilitate double-sided tape punching. Foam double-sided tape has the characteristics of strong adhesion, good retention, good waterproof performance, strong temperature resistance and strong UV protection. Foam foam substrates are divided into: EVA foam, PE foam, PU foam, acrylic foam and high foam. The glue system is divided into: oil glue, hot sol, rubber and acrylic glue.
