Definitions
- the present invention relates to an adhesive tape, in particular for joining at least two objects or closing and securing a package consisting of a carrier tape which is coated on at least one side with a pressure-sensitive adhesive.
- the pressure-sensitive adhesive coating applied on at least one side can be full-surface. But it is also possible that only a partial coating is present.
- the coating can be applied with adhesive strip or punctiform. This can reduce the consumption of adhesive. It is essential, however, that a surface area which is sufficient for reliable fixing of the adhesive tape is coated with pressure-sensitive adhesive.
- a stretchable plastic tape which has at least one area with a pressure-sensitive adhesive is known from the European patent EP 0 680 440 B1.
- the pressure-sensitive adhesive does not cover the entire length of the plastic tape.
- the extensibility in the longitudinal direction of the adhesive tape is at least 150%, and the tape has an elasticity of less than 30% remind ⁇ position.
- the adhesive tape is used for bundling and / or fixing objects.
- the tape should be able to be cut at the same time without the use of scissors or a knife at the desired location.
- an adhesive tape of the type mentioned above in that the adhesive tape has a permanently elastic extensibility of 5 to 50% and has at least one of its longitudinal edges a plurality of notches, which is a severing of the adhesive tape without application allow a tool.
- the percentage extensibility is based on the initial length of the unloaded adhesive tape.
- the adhesive tape has a permanently elastic extensibility of 10 to 25%.
- the carrier tape advantageously has a provision of 60-100%, preferably 80-95%.
- a provision is understood to mean the shortening of the adhesive tape after the end of an expansion. The extent of the provision is related to the elongation caused by the elongation and expressed as a percentage.
- a default of 60% means that after stretching, 40% of the additional length is retained as a permanent extension of the tape.
- the material of the carrier tape may be selected from a variety of polymeric materials.
- polyolefins such as polyethylene including HDPE (high density polyethylene), low density polyethylene, linear low density polyethylene and linear very low density polyethylene, polypropylene and polybutylene, vinyl copolymers such as plasticized and non-plasticized poly (vinyl chloride) and poly (vinyl acetate); olefinic copolymers such as ethylene / methacrylate copolymers, ethylene / vinyl acetate copolymers, acrylonitrile-butadiene-styrene copolymers and ethylene / propylene copolymers; acrylic polymers and copolymers and combinations of these materials.
- Mixtures and Blends of plastics or of plastic and elastomeric materials such as polypropylene / polyethylene, polyurethane / polyolefin, polyurethane / polycarbonate and polyurethane / polyester may also be used.
- the carrier tape may also be formed as a fabric tape or as a nonwoven tape.
- the carrier tape made of a rubber-elastic material.
- a thermoplastic elastomer in particular a material which is selected from the group consisting of polyesters, polyurethanes, styrene copolymers and polyolefins.
- the pressure-sensitive adhesive arranged on the carrier tape is advantageously selected from the group consisting of polyesters, polyurethanes, styrene copolymers and polyolefins.
- the adhesives based on acrylates can not be water-soluble or water-soluble, it may, for. B. be copolymers of isooctyl acrylate and acrylic acid. As a synthetic rubber z. As polyisoprenes, polybutadiene, styrene-isoprene-styrene and styrene-butadiene-styrene block copolymers and other elastomers in question.
- the adhesives may be in the form of dispersions.
- the adhesive coating with a basis weight of 40 to 200 g / m 2 , preferably applied from 70 to 130 g / m 2 on the carrier tape.
- the indentations arranged on at least one longitudinal edge are advantageously triangular or semi-circular.
- the notches are arranged at a small distance from each other, preferably immediately adjacent with no gaps.
- the thickness of the carrier tape varies according to the field of application. For manual applications, ie for daily use, a thickness of the carrier tape of 10 to 250 microns is preferred.
- the thickness of the adhesive layer may vary in the range of 5 ⁇ m to 1000 ⁇ m. Preferably, a layer thickness of 20 microns to 250 microns is used.
- the adhesive tape is preferably rolled up into a roll, from which the consumer can unroll and tear off pieces of any length.
- the elastic carrier tape and the adhesive coating are matched to one another in such a way that the carrier, including the adhesive coating, can be torn by hand transversely to its longitudinal direction.
- the adhesive tape according to the invention allows the binding of the most diverse objects together. So z. B. everyday, offered in supermarkets in bulk form items such as bottles, cans, cardboard boxes façadege ⁇ bound and carried away in a very simple way. This can be done both by the customer and by the dealer, who already binds in his offer a certain number of these items and offers them as a unit, such. B. several beverage cans and bottles in a tied shape.
- the carrier tape has a solvent-free or solvent-containing PSA, which z. B. by coextrusion, melt coating or dispersion coating is produced, said adhesive is connected by means of a flame or corona pretreatment or a primer layer, which is applied by co-extrusion or coating, with the surface of the support material. It is also possible to use an intermediate film as a so-called release liner.
- the substrate used was a natural latex film (natural latex grade 24-005 NR, OP latex insert from Wolff, Mörlenbach).
- a water-based acrylate dispersion (Acronal V 212 / BASF) was applied to a surface of 20 cm width and 30 cm length by means of a laboratory doctor blade device (spiral doctor 50). After the dispersion had dried thoroughly (open drying at 24 ° C., about 65% atmospheric humidity, 24 hours drying time), a continuous pressure-sensitive adhesive film resulted.
- the adhesive properties of the pressure-sensitive adhesive film on the latex support were retained, even after 100% elongation of the support material (natural latex film). A detachment of the pressure-sensitive adhesive film from the carrier material (natural latex foil) was not observed.
