The size of recycle bag is determined by size of the objects. The bag sizes have no uniform standards. It will be designed and produced according to the actual needs.
The must common used bags such the non woven bag China with A3 paper size are: 32cm (width) * 43cm (H) * 10cm (bottom width and side width). The mobile belt length is 50cm, the width is 2.5cm, which is most often used in various business units. Supermarkets use the bigger bags. Size: 48 (W) * 35 (H) * 10 (bottom width and lateral width). The length of hand bags is 50cm and the width is 2.5cm.
Beautiful bags are not just commodity bags. Their beautiful appearances are more attractive and can be the embodiments of simple fashion shoulder bags becoming beautiful landscapes in streets. With its solid, waterproof, sticky characteristics will become the first choice of customers to go out with such a rept bag. The company's logo or advertising can be printed on it and the advertising effect will be obviously. It is real small investment with a large return.
General dry goods, it is recommended to use the nation's waste or European waste in accordance with A or B grade kraft liner technical indicators to control the production of base paper. Surface layer of noodles, noodles, according to printed patterns and advertising. Quantitative sheet can be 135 to 150 g / m2. 25 * 20 * 15cm paper bag bear the weight of up to 15 kg. The goods need to withstand some moisture, you can also make use of waste paper. Only on the basis of the above criteria, to add 0.5 to 1.0% wet strength agent, wet strength 10 to 15 percent of the dry strength can. For meat or other wet, the same can be selected full of waste paper to manufacture shopping bags. This needs to be added to the pulp in the papermaking process, or coated with environmentally friendly anti-oil. Kraft liner board, the second spray of water-soluble or degradation of type resin can also use good surface strength.
In recent years, many manufacturers in China have developed full waste folder tendons paper. It means that adding to water-soluble yarn between two layers of slurry combining with textile principle. The paper layer can reach the strength of the four-layer kraft paper and completely replace the ordinary cement bag paper. Similarly, the single-layer paper can be used in rept bags.

Exploring the Potentials of Nano-Aluminum Powder
Nano-aluminum powder, a material with remarkable properties due to its minuscule particle size, is revolutionizing various industries with its high reactivity and large specific surface area. Unlike its bulk counterpart, nano-aluminum powder begins to oxidize at a lower temperature of 550°C, compared to the 950°C oxidation point of ordinary aluminum. This lower ignition energy and full combustion without apparent cohesion make it a superior choice for applications requiring high energy and efficiency. The unique characteristics of nano-aluminum powder, such as faster burning rates and greater heat release, are largely influenced by its synthesis method, which determines its particle size, surface area, and shape.
