Handbag, as its name implies, is a bag for holding articles and carrying them easily. Its load-bearing function determines its material and form. According to the materials used, it can be roughly divided into paper handbags, plastic bags, cloth bags, small baskets and baskets in a wide sense. The most common and frequently used bags should be paper composite bags and plastic bags, followed by cloth bags, small baskets and baskets are rare in metropolitan areas.
纸手提袋
Paper bag
纸手提袋大多数是用厚重的牛皮纸、白卡纸、灰底白卡纸、白底白卡纸和铜卡纸,通过胶印机印刷、模切、粘和成型。由于印刷技术和设备的现代化,印刷图案非常精美、细腻、表现形式丰富,现代印刷中的所有工艺都可以在一个小小的手袋上表现出来,如烫金、凹凸、UV、模切异型等。
Paper handbags are mostly made of heavy kraft paper, white cardboard, white cardboard with grey background, white cardboard with white background and copper cardboard, which are printed, die-cut, bonded and formed by offset press. Due to the modernization of printing technology and equipment, the printing pattern is very exquisite, delicate and rich in forms. All the processes in modern printing can be displayed on a small handbag, such as hot stamping, concave and convex, UV, die cutting profile, etc.
由于材料的差异,牛皮纸的挺度和韧性较好,表面也比较粗糙,而且带有底色,一般不适合4色印刷,只做一些单色印刷,也不用在表面覆膜,其生产成本在1.5元左右(对开)。牛皮纸手提袋在粘合成型时要注意用质量好的胶水,否则会出现穿底和爆口的现象。同时,牛皮纸手提袋放置时间过长也会出现脱胶现象。而白卡纸、灰底白卡纸、白底白卡纸和铜卡纸都有一个共同的特点,表面细腻,都是白色,适合4色印刷,能印刷出非常精美的图案,由于纸张本身韧性和怕水的特性,通常印刷后都要在表面进行覆膜处理(BOPP膜,也叫双向拉伸聚丙烯薄膜,称这样的纸袋为纸塑复合袋),增加它的韧性和耐水性,进行覆膜处理后的手袋一般不会出现脱胶现象,其生产成本在1.3~2.0元,铜卡纸手袋成本{zg},其次是白卡纸手袋、灰底白卡纸手袋、白底白卡纸手袋。
Due to the difference of materials, kraft paper has better stiffness and toughness, rough surface, and with background color. It is not suitable for 4-color printing. It only does some monochrome printing, but also does not need to cover the surface. Its production cost is about 1.5 yuan (opposite). Careful attention should be paid to the use of good quality glue in the bonding process of kraft paper handbags, otherwise the phenomenon of bottom piercing and bursting will occur. At the same time, kraft paper handbags will degum if they are placed too long. White cardboard, grey-bottom white cardboard, white-bottom white cardboard and copper cardboard all have a common feature, the surface is delicate, are white, suitable for four-color printing, can print very beautiful patterns, because of the paper's own toughness and water-proof characteristics, usually after printing, the surface is coated (BOPP film, also known as biaxially stretched polypropylene film, called paper-plastic composite bag. Close the bag, increase its toughness and water resistance, the handbags after film coating will not degum generally. Its production cost is 1.3-2.0 yuan. Copper cardboard handbags have the highest cost, followed by white cardboard handbags, white cardboard handbags with grey bottom and white cardboard handbags with white bottom.
塑料袋
Plastic bag
塑料袋根据使用的材料,分为普通塑料袋和可降解塑料袋。一般农贸市场提供的塑料购物袋厚度在0.005毫米左右,大型超市和商场提供的塑料购物袋厚度一般在0.015毫米~0.020毫米,目前市场80%以上的塑料购物袋厚度都无法达到0.025毫米以上的国家限塑标准。限塑后,大型超市和商场都有偿使用塑料购物袋,也有商场使用可降解塑料袋。
According to the materials used, plastic bags can be divided into ordinary plastic bags and degradable plastic bags. Generally, the thickness of plastic shopping bags provided by farmers'markets is about 0.005 mm. The thickness of plastic shopping bags provided by large supermarkets and shopping malls is generally between 0.015 mm and 0.020 mm. At present, more than 80% of the thickness of plastic shopping bags in the market can not meet the national plastic limit standard of 0.025 mm or more. After plastic restriction, plastic shopping bags are paid for in supermarkets and shopping malls, and degradable plastic bags are also used in shopping malls.
布袋
Cloth bag
布袋根据使用的材料是否需纺织,可以分为纺织布和不织布。纺织布分为植物纤维布和化学纤维布及混纺布;不织布通常又叫无纺布,英文名为NonWoven,是一种非织造布,它是直接利用高聚物切片,短纤维或长丝将纤维通过气流或机械成网,然后经过水刺、针刺或热轧加固,{zh1}经过整理形成的无编织的布料,具有柔软、透气的新型纤维制品,优点是不产生纤维屑、强韧、耐用、丝般柔软,而且还有棉质的感觉,和棉织品相比,无纺布袋子容易成形且造价便宜。
Cloth bags can be divided into textile and non-woven fabrics according to whether the materials used are textile or not. Textile fabrics are divided into vegetable and chemical fibre fabrics and blended fabrics; nonwoven fabrics, also known as NonWoven in English, are non-woven fabrics, which directly use polymer chips, short fibers or filaments to form a network through air flow or mechanical, and then through spunlace, needle punching or hot rolling reinforcement, and finally through finishing to form non-woven fabrics, which are soft and transparent. Compared with cotton fabrics, non-woven bags are easier to form and cheaper in cost.
纺织布袋多采用棉布、帆布、涤棉布、牛津布等材料,这些布料表面粗糙,无法直接精细印刷,多采用丝网印刷或转印。同时,由于原材料的价格高,生产的手袋也较昂贵。
Textile bags are mostly made of cotton, canvas, polyester, cotton and Oxford fabrics. These fabrics have rough surfaces and can not be printed directly and finely. They are mostly screen printing or transfer printing. At the same time, because of the high price of raw materials, the handbags produced are also more expensive.
小篮子和小筐子
Small baskets and baskets
小篮子和小筐子多用竹、木、藤加工而成,提携物品结实耐用,一般是工艺品,价格昂贵,不便携带,产量和使用量都不大。
Small baskets and baskets are made of bamboo, wood and rattan. They are usually handicraft products with strong and durable properties. They are expensive and not portable, and their output and usage are not large.
