Manufacturing method for multifunctional composite material bottle

Abstract

The invention relates to a manufacturing method for a multifunctional composite material bottle. The method comprises the steps that a bottle mouth and bottle shoulder part, a bottle body part and a bottle bottom part are formed separately, the bottle body part is formed by winding a sheet material, and all the parts are connected into a whole through a welding technology. According to the method,due to the fact that the multiple parts are combined, different functional composite materials can be selected according to needs for the materials of all the parts so as to be combined and formed, and therefore compared with an existing traditional bottle making process product, the processing technology is simpler, a blow-injection mode does not need to be manufacture, the manufacturing cost can be greatly lowered, the manufacturing time can be greatly shortened, and rapid and mass production can be facilitated; in addition, combined addition of the functions except common requirements canbe realized, such as excellent printing of a bottle body, hot filling, high barrier property, high transparency and other special requirements; and meanwhile, the product has the characteristics of being low in production cost, environmental-friendly in production process, free of emission of highly toxic waste gas, light and capable of saving the transportation cost in every links such as production and use.

Description

technical field [0001] The invention belongs to the field of plastic bottles, and in particular relates to a method for manufacturing a multifunctional composite material bottle. Background technique [0002] At present, most of the packaging bottles commonly used in the market are made of plastic, metal, glass and other materials. Plastic bottles are mostly made of single-layer materials, which usually do not have high barrier properties; even a small amount of multi-layer composite plastic bottles cannot have high barrier / high transparency / heat-resistant perfusion properties due to process limitations, and the cost is abnormally high There is a defect of easy delamination. At the same time, these bottles (including glass bottles) cannot be directly printed on the bottle body, but can only be simply printed or labeled, and the appearance display is limited; while metal or glass bottles, although they have high Barrier or transparent high barrier performance, there are defe...
