The idea of strange new packaging of foreign
To the benefits of new food and beverage containers. Recently by the Canadian company successfully developed and patented. The container consists of two parts. Part for the bloom, the thin containers used for food preservation. May be plastic, metal or glass; the other is embedded in the outer structure for the container may be made of cardboard. The new container seal. Ling can be cold, heat, corrosion, and disinfection. Is semi-rigid or rigid containers as an ideal substitute. Material composition in such containers, the cardboard about 80% 90%, while plastic, metal or glass can be installed according to the selected food items, usually only 10% to 20%. Board of environmental pollution, biodegradable, can also be recycled and reused. As used in this container of plastic, metal or glass on the market than the composition of food containers used much less. Therefore,[link widoczny dla zalogowanych], relying on help to clarify the issue of waste and garbage, greatly reducing soil, water and air pollution. Mino materials in recent years with a fresh package to control and inhibit the rapid aging of fresh food to prevent decay of the new generation of food packaging materials, the rise of the development work is in Japan. It was found that different vegetables and fruits with different amounts of ethylene gas to destroy the mature, but also found a small amount of vegetables and fruits will be rotten produce some ethylene gas that will further encourage other cooked vegetables and fruits quickly and lead to decay. Therefore, if the control absorption of ethylene gas that we can achieve preservation of the storage material. According to this principle, the Japanese Association of the food distribution system has developed a spar with a powder to punish the corrugated side; Showa Biochemical Company, as the raw material of calcium phosphate mineral will concentrate re-infiltration into the absorbent paper in the wrapping paper; Ma Asahi Glass the company tried to a high purity calcium phosphate or a blend of new polyethylene film packaging film, or mixed within the corrugated packaging material made of a new. Such new packaging materials all have the function of absorbing ethylene gas. Both carbon dioxide and calcium phosphate also inhibit the role of chlorophyll decomposition. It is said that the preservation of comparable efficacy and refrigerated trucks. Mino new package of high nitrile materials of polyacrylonitrile () has a very good performance and excellent gas resistance by many chemical properties. But it can not melt processing, it can not heat molding, make the application affected. With acrylic or styrene monomer copolymerization, a system of high nitrile polymer (referred to as the HNP), not only to maintain the good performance of the original PAN, and the significant improvement in processing performance can be thermoformed. The HNP has a transparent, low gas permeability, excellent chemical resistance so that it can be used as packaging resin. In addition, the high hardness and low density makes it economically with wc, that most of,[link widoczny dla zalogowanych], PET, and the Ps in some situations than competitive. Prepared by the HNP lightweight thermoformed packaging materials, compared with many other competitive materials. Shorter production cycle,[link widoczny dla zalogowanych], waste less. HNP is normally acrylonitrile: methyl acrylate (75:25) copolymer. HNP is a time in the processing of viscous shear-sensitive materials, and hardware Pvc similar situation. However,[link widoczny dla zalogowanych], better thermal stability than Pvc. And Pvc difference is in the process does not produce corrosive gases, process equipment element to be chrome plated. Also under the conditions of HNP in the l30 ℃ maximum line tension was I8-2 ~ cm / em. Better than PVC, 1lcm/cm. HNP heat molding products dimensional stability curve shows that, HNP elastic resin is about 145 ~ C when the minimum. However, because of HNP has a high melt strength, so even in the 145 ℃, the flexibility of the material remains evenly distributed. Application of hot melt Canadian cricket in Canada is Canada's largest public food company in the packaged food processing plants,[link widoczny dla zalogowanych], and its main products are powdered drinks, breakfast cereals, puddings, jellies and so on. Result of these diverse product line speed of different packaging. Packaged product and the carton or carton box and weight is not one. For example, pudding powder packaging line package fast. The packaging of cereal slow; packaged pudding after the cartons (boxes) Small and light weight, and generally higher cereal packaging. Cartons and cartons of effective sealing is an important thing, according to different packaging requirements of speed and adhesion strength. Equipped with the appropriate adhesive and the glue is required. Over the past with five different plant materials and adhesives, adhesive is made to replace all the plant. Today, only one sealing job online snake hot melt glue a 57 HM Jing, from a vendor production. HM 5782 is a light-colored EVA hot melt, by the Canadian H. B. Fuller production. A single hot melt adhesive can be applied to a wide variety of packaging, and the operation is quite simple and convenient. ● China Packaging 2O00 Volume 20 No. 3 97
