Q. What is Bopp Self Adhesive Packaging Tape?
A. This is a kind of Pressure sensitive tape.

Q. What is a Pressure Sensitive Tape?
A. A pressure sensitive tape is any adhesive tape that will stick to a wide variety of clean dry surfaces with only the minimum of pressure applied. It is ready to use and does not need to be activated by water, solvent or heat.

A pressure sensitive tape consists of a relatively thin, flexible backing or carrier, coated with an adhesive, which is permanently sticky at room temperature. The tapes can be manufactured with the adhesive coating on one side (single-sided) or both sides (double-sided) of the carrier.

Q. What is the backing that you use for your tapes?
A. For our Packaging tapes we use BOPP Film (Biaxially Oriented Poly Propylene). For our Protetection film / Tapes we use a vide variety of Backing depending upon the use of film. The most common ones are LLDPE/HDPE, BOPP, and Polyester.

Q. What is the type of Adhesive that you use for your tapes?
A. We use Water based Acrylic Adhesive. Acrylics are fully synthetic polymers, which are manufactured to give the specific adhesive properties required. Acrylic adhesives are more expensive but generally have better resistance to ageing and exposure to light.

Q. The other type of Adhesive which we do not use and why?
A. Rubber/resin adhesive is a mixture of a rubbery material and a hard resin. The rubber and the resin can come from natural or synthetic sources. The natural materials are usually extracted from trees while the synthetics come from the oil industry. Rubber/resin adhesives are relatively cheap but, unless they are specially formulated through curing or stabilizing, do not have very good resistance to heat, ageing or exposure to light.

Q. How is tape produced?
A. There are 2 processes in the production of pressure sensitive tape; coating and slitting. Coating is the application of the adhesive on to the carrier. Slitting is the cutting up of a huge 'jumbo' roll of coated carrier film into the large and small rolls of tape as we see them in the shops.

Coating:
Since pressure sensitive adhesives are not runny liquids, they are not as easy to coat on to the thin flexible carriers, therefore they must be made less viscous (or thin) to make coating possible. The adhesive materials are mixed with water to form an emulsion or dispersion. This is then coated onto the backing and the coated film is passed through a series of Heated Ovens where the water in the adhesive is evaporated.

Slitting:
The coating process has now made a 'jumbo'. This is what we call a huge roll of tape, perhaps 1.6m wide x 6000m long. It is the slitting process that turns the large jumbo into rolls for sale, in the sizes we all know. These could be anything from 12mm to 288 mm. The jumbo is unwound onto a machine that contains a number of razor blades. The number and distance between these blades determines the width of the tape. The carrier passes over these blades cutting the tape into narrower widths and these are then wound on to cores to give the appropriate length for the finished rolls.


Q. Why doesn't tape stick to itself on the Roll?
A. Pressure sensitive adhesives easily stick to a wide range of different surfaces including Cellulose film. So why does the tape not stick to itself? In order that we can use tape and easily pull it off the roll we need to treat the back of the carrier with a special treatment. The film that we use is already treated. This may not be obvious straight away but it is a very important part of the tape. The release coating not only ensures that the user can easily unwind the roll but it makes slitting.
