How Are Adhesive Tapes Made?

Adhesive Tapes are our everyday user-friendly household tools. They are versatile and simple to use. Nonetheless, the production of adhesive tapes is not as simple as its function. Let’s delve into the manufacturing process of adhesive tapes to understand all the work that goes into producing them.

The Production

The entire manufacturing process of one roll of adhesive tape consists of three crucial steps. Initially, the cellulose acetate backing is prepared, and afterwards the glue is made. After the two products are integrated, the final product is cut into little sets for individual consumer use, evaluated, packaged, and shipped off to suppliers.

Firstly, wood pulp or cotton seeds are broken down into cellulose fibres through both manual crushing, and also chemical disintegration. Next, the raw cellulose fibre is treated.

Acetic acid and acetic anhydride are mixed to develop triacetate. It is then treated with a mix of chemicals and also water to make cellulose acetate. After being warmed to eliminate all wetness, the cellulose acetate is mixed with a plasticizing product similar to oil. The resulting cellulose acetate plastic is formed into pellets, or pelletized. The pellets are dissolved into fluid then spread over a broad, level conveyer belt to form exceptionally thin plastic sheets. The completed tape backing is after that looped on large rolls for the application of the glue.

Making the Adhesive

Modern glue made from adhesomers are sufficiently sticky. Such polymers are made from crude oil distillate that is chemically reacted to develop acids and alcohols. These products are after that combined with a hydrocarbon solvent that catalyzes their polymerization. The resulting adhesomer can be used in this way or undergo go further melting with solvents, according to its desired application.

Incorporating Film to Glue

The next step is to apply the glue to the film. The non-adhesive side of the backing is treated with a release agent that makes the tape very easy to loosen up. Prior to the glue application, the adhesive side might be treated with a primer to anchor the glue. This glue coating is applied by routing the film over a large roller that turns in an open vat of primer. As soon as these surface areas are coated the tape travels over heat emitting drums to dry it. An extremely thin layer of pressure delicate glue is applied onto the primed side of the tape, which is then rolled into ovens for drying under high temperature.

Tape Is Rolled, Cut and Packaged

As soon as the tape dries out, the tape is curved onto huge big rolls and transmitted over slicers that split it into varying widths. The bands of tape are then wound around a tiny plastic core, which is then fitted inside a plastic dispenser with a serrated edge to cut different sizes of tape. Both tape rolls and also dispensers come in different sizes to fit client demands.

As you can see, there is a lot of effort that goes into manufacturing adhesive tape. The next time you are using one, remember to use it with care to avoid any wastage.
