复合包装袋的制作的特点分析!
发布于:2021/07/13 首先把各种不同特性的资料复合在一起,来改 善包装资料的透气性、透湿性、耐油性、耐水性、耐药品性,使其发挥防虫、防尘、防微生物、对光、香、臭等气味的隔绝性,以及耐热、耐寒、耐冲击具有更好的机械强度和加工合用机能,并有杰出的印刷及装修作用。
First of all, all kinds of materials with different characteristics are combined to improve the air permeability, moisture permeability, oil resistance, water resistance and drug resistance of packaging materials, so as to give full play to the anti insect, anti dust, anti microbial, isolation from light, fragrance and odor, as well as heat resistance, cold resistance and impact resistance, with better mechanical strength and processing function, And has the outstanding printing and the decoration function.
依照包装的办法分类:三边封、阴阳袋、中封、枕型袋、五边封袋、自立袋、拉链袋、吸管袋、卷材、盖材等按功能分类:高阴隔阂袋、蒸煮膜袋、抗静电膜袋、抗 菌膜袋、防雾膜袋、真空袋、抗化学膜袋、除氧包装膜袋、气调包装膜袋等按原料分类为:镭射镀铝膜复纸资料、镭射转移纸资料、纸复合资料、铝复合资料、塑料复合资料、织物复合资料等。
According to the method of packaging: three side seal, Yin Yang bag, middle seal, pillow bag, five side seal, self-supporting bag, zipper bag, straw bag, coil, cover material, etc. according to the function classification: high shade barrier bag, cooking film bag, antistatic film bag, antibacterial film bag, antifogging film bag, vacuum bag, anti-chemical film bag, deoxidizing film bag According to the raw materials, modified atmosphere packaging film bags are classified as: laser aluminized film lamination information, laser transfer paper information, paper composite information, aluminum composite information, plastic composite information, fabric composite information, etc.

在工业上,也包含乙烯与少量α-烯烃的共聚物。聚乙烯无臭,无 毒,手感似蜡,具有优良的耐低温机能(低运用温度可达-70~-100℃),化学不乱性好,本领大多数酸碱的腐蚀(不耐具有氧化性质的酸),常温下不溶于一般溶剂,吸水性小,电绝缘机能优良;但纸塑复合袋聚乙烯的性质因品种而异,主要取决于分子结构和密度。
In industry, it also contains ethylene and a small amount α- Copolymers of olefins. Polyethylene is odorless, nontoxic and waxy. It has excellent low temperature resistance (low operating temperature can reach - 70 ~ - 100 ℃), good chemical stability, most acid-base corrosion (not resistant to oxidizing acid), insoluble in general solvents at room temperature, low water absorption and excellent electrical insulation; However, the properties of PE for paper plastic composite bags vary from variety to variety, mainly depending on the molecular structure and density.
纸塑复合袋选用不同的出产办法可得不同密度(0.91~0.96g/cm3)的产品。聚乙烯可用一般热塑性塑料的成型办法(见塑料加工)加工。用途十分广泛,主要用来制作薄膜、容器、管道、单丝、电线电缆、日用品等,并可作为电视、雷达等的高频绝缘资料。选用抗滑度在25度以上的牛皮纸制作,轻易叠放;
Different densities (0.91-0.96g / cm3) of paper plastic composite bags can be obtained by different production methods. Polyethylene can be processed by the molding method of general thermoplastic (see plastic processing). It is widely used for making films, containers, pipes, monofilaments, wires and cables, daily necessities, etc. it can also be used as high-frequency insulation materials for TV, radar, etc. Choose the kraft paper with the skid resistance of more than 25 degrees to make it easy to stack;
防潮性好,便于装卸,以人力或叉车完成单元化运送,现在流行和有用的普通包装资料。水溶纱复合包装袋是由复合袋机工艺技术制成的纬纱接连盘绕无中缝的新型包装袋。纸纱复合包装袋其结构为表里二层世界纸袋纸,中间粘结网状维纶水溶纱,牛皮纸袋三位一体复合而成。因为维纶水溶纱未经缩醛处理能溶解于80℃的热水,运用过的废袋经水解后收回再 生使用,不污染环境。
Good moisture-proof, easy to load and unload, with manpower or forklift to complete the unit delivery, now popular and useful general packaging information. Water soluble yarn composite packaging bag is a new type of packaging bag which is made by the technology of composite bag machine. The structure of the paper yarn composite packaging bag is composed of two layers of world paper bag paper on the inside and outside, water-soluble PVA yarn bonded in the middle and kraft paper bag. Because vinylon water-soluble yarn can be dissolved in 80 ℃ hot water without acetal treatment, the used waste bag can be recycled after hydrolysis, which does not pollute the environment.
