As we all know, paper is a recyclable resource. The raw material of paper making is mainly plant fiber. In addition to cellulose, hemicellulose and lignin, there are other components with less content, such as resin and ash. In addition, there are auxiliary ingredients such as sodium sulfate. In addition to plant fiber, paper also need to add different fillers according to different paper materials. Plastic bags are usually made from polyethylene and made from petroleum, which is already our energy shortage. Paper bags, by contrast, are made from trees, a renewable resource. Its degradable and recyclable features are naturally labeled with green labels.
Not all paper bags are degradable. Some paper bags are covered with plastic film. If the film material is POLYvinyl chloride, it will not only harm human health but also affect the normal decomposition of the paper material. In addition, the production of paper is still based on the use of logs, excessive production of paper bags, resulting in a large number of trees felled, will also damage the environment. Paper making technology is not mature, so that the production process produces a large amount of waste water and waste gas if the treatment equipment is backward will lead to untreated or incomplete treatment on the discharge, still can pollute the environment.
Shanghai packaging bag design in 2012 is different from the past, Shanghai packaging bag is a very old manual industry. But now in order to high efficiency, save manpower and cost, usually adopt machine to process. Nowadays paper bags are mainly divided into ordinary packaging bags and exquisite shopping bags. This is also the 2011 edition of the hand-held paper bag. So how are these two kinds of paper bags made? Hua Yang introduction. Ordinary paper bags are mainly produced by rotary paper bag printing machine. The production efficiency of this method is high, but its disadvantages are also obvious, that is, the paper bag is rough and not delicate. And exquisite shopping bags are mostly made of sheet paper, and then printed in color, and then mounted on PP or bronzed. And then by the paper bag factory for manual or semi-automatic machine production [1], usually using artificial rope, knot as handle, and then complete the production of paper bags.
The advantage of this kind of shopping bag is that any shape of paper can be made into a hand-held paper bag. But this mode of production, production efficiency is low. This type of paper bag, used for some noble goods packaging, as a gift bag. Or in some commercial activities as an advertising bag. Of course, the exquisite and beautiful hand-held paper bag has become a convenient shopping bag for ladies. At the same time, it is also the extension of corporate image and commodity advertising. In the production of shopping bags, in addition to pay attention to the structure of close, do not take off the bottom, but also the pursuit of environmental protection, beautiful, delicate and durable. If you still worry about handbag design, it is better to refer to the handbag design products of Huayang. The new hand-held paper bags in 2011 mainly tend to be environmentally friendly, durable and beautiful. In the production method also had better promotion and improvement.
