The invention discloses modified polyethylene and an easy removing suppository packaging film. The raw materials of the modified polyethylene comprise according to the parts by weight: 100 parts of polyethylene and 5-40 parts of polybutene or modified polybutene. The easy removing suppository packaging film comprises a barrier layer and a heat-sealing layer. The barrier layer is an aluminum foil layer and a polyvinyl chloride layer. The barrier layer and a heat-sealing layer are compounded together by a gluing mode. The heat-sealing layer is composite layer structure and sequentially one to two-layer polyethylene layer and one-layer modified polyethylene layer along the direction far away the barrier layer. Raw materials used by the modified polyethylene layer are 100 parts of polyethylene, and 5-40 parts of polybutene or modified polybutene according to the parts by weight. The heat-sealing layer has good easy removing performance after lap piling and heat-sealing.

The invention discloses an anti-pollution low-temperature heat-sealing polyethylene film easy to tear off. The polyethylene film consists of the following components in part by weight: 45 to 65 parts of polyethylene resin, 15 to 30 parts of EVA (ethylene-vinyl acetate) and 3 to 5 parts of an additive. According to the invention, the polyethylene resin is modified by matching of EVA and the additive; when the prepared polyethylene film is made into a plastic package, a sealing temperature is low, so that the phenomenon of false sealing is effectively avoided; after the plastic package is sealed, the polyethylene film is still easy to tear off, so that the use convenience is improved.

The invention discloses a special easy-peel heat sealable film for a Tyvek sanitary bag. The film is made from 100 parts of polyethylene and 10-50 parts of polybutene or modified polybutene by weight. When the film is subject to thermal sealing with Tyvek material, two layers of materials have proper cohesive force therebetween, can bear articles, be easily torn, and convenient for use.

The invention provides a copper printing paper self pasting label belt without backing paper. The copper printing paper self pasting label belt comprises labels and tearing lines, wherein the labels are mutually connected through the tearing lines, each label consists of a silicon oil layer, a lamination layer, copper printing paper and a glue coating layer, one lamination layer coats the printing surface of the copper printing paper, the silicon oil layer costs the surface of the lamination layer, the glue coating layer coats the reverse surface of the printing surface of the copper printing paper, an easy-to-tear block extends from the copper printing paper at each corner of each label, a tearing line is arranged between the easy-to-tear block and the label, and the label belt is rolled into a roll shape in a mode that the glue coating layer faces the inward side. Through the design without the backing paper, the resource waste is reduced, and the cost is lowered; through the adoption of the tearing lines, the use mode that the traditional labels need to be sheared in the use process is changed; the lamination layer coats the surface of the copper printing paper, the characters and patterns on the surface of the labels can be effectively protected; the labels can be easily peeled off and torn down through the easy-to-tear block, and the use is convenient; the tail end connecting point width of each tearing line is smaller than 0.01mm, the tearing is easy, and in addition, the attractive appearance of the label is not influenced.

The invention discloses medical adhesive tape. The tape comprises a substrate layer. A gel coating layer is connected with the substrate layer. Clearances are provided between gels in the gel coating layer. Two sides of the adhesive tape stripe are provided with two elastic bands. Ventilation holes are formed on a cloth stripe. The center of the cloth stripe is provided with antimicrobial pledget. Two ends of two elastic bands are correspondingly provided with nylon adhesive buckles for connection purposes. The medical adhesive tape can make the skin contact with the air through the substrate layer to attain the effect of ventilation, moisture permeation and the allergy reduction, reduce the patient's pain brought by the tearing off the tape, effectively facilitate the medical personnel to tear open the adhesive tape. The tape has the advantages of being simple in structure, convenient to use, low in production cost, capable of reducing pollution, and therefore possessing good practicality.
