復合包裝袋的制作特點
發布于:2021/06/29
首先把各種不同特性的資料復合在一起,來改善包裝資料的透氣性、透濕性、耐油性、耐水性、耐藥品性,使其發揮防蟲、防塵、防微生物、對光、香、臭等氣味的隔絕性,以及耐熱、耐寒、耐沖擊具有更好的機械強度和加工合用機能,并有杰出的印刷及裝修作用。
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.
依照包裝的辦法分類:三邊封、陰陽袋、中封、枕型袋、五邊封袋、自立袋、拉鏈袋、吸管袋、卷材、蓋材等按功能分類:高陰隔閡袋、蒸煮膜袋、抗靜電膜袋、抗菌膜袋、防霧膜袋、真空袋、抗化學膜袋、除氧包裝膜袋、氣調包裝膜袋等按原料分類為:鐳射鍍鋁膜復紙資料、鐳射轉移紙資料、紙復合資料、鋁復合資料、塑料復合資料、織物復合資料等。
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.
在工業上,也包含乙烯與少量α-烯烴的共聚物。聚乙烯無臭,無毒,手感似蠟,具有優良的耐低溫機能(低運用溫度可達-70~-100℃),化學不亂性好,本領大多數酸堿的腐蝕(不耐具有氧化性質的酸),常溫下不溶于一般溶劑,吸水性小,電絕緣機能優良;但聚乙烯對于環境應力(化學與機械作用)是很敏感的,耐熱老化性差。紙塑復合袋聚乙烯的性質因品種而異,主要取決于分子結構和密度。
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, polyethylene is very sensitive to environmental stress (chemical and mechanical action) and has poor heat aging resistance. The properties of PE for paper plastic composite bags vary with different varieties, mainly depending on the molecular structure and density.
紙塑復合袋選用不同的出產辦法可得不同密度(0.91~0.96g/cm3)的產品。聚乙烯可用一般熱塑性塑料的成型辦法(見塑料加工)加工。用途十分廣泛,主要用來制作薄膜、容器、管道、單絲、電線電纜、日用品等,并可作為電視、雷達等的高頻絕緣資料。選用抗滑度在25度以上的牛皮紙制作,輕易疊放;
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,便于裝卸,以人力或叉車完成單元化運送,現在流行和有用的普通包裝資料。水溶紗復合包裝袋是由復合袋機工藝技術制成的緯紗接連盤繞無中縫的新型包裝袋。紙紗復合包裝袋其結構為表里二層世界紙袋紙,中間粘結網狀維綸水溶紗,牛皮紙袋三位一體復合而成。因為維綸水溶紗未經縮醛處理能溶解于80℃的熱水,運用過的廢袋經水解后收回再生使用,不污染環境。
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.
