Description

Paper plastic handle and manufacturing method thereof

The invention relates to a paper-plastic handle and a manufacturing method thereof, in particular to a paper-plastic handle manufactured by dry hot pressing, which can be used with a paper-plastic box, and can be recycled, naturally decomposed, and weighted. Light, high load resistance and many excellent characteristics.

Press, when you buy goods, you will usually have appropriate packaging. For example, when you buy foods such as biscuits and candy, you will use beautiful paper bags or packaging boxes. When you buy shoes, there will be shoe box packaging. When you purchase 3C products, you will also have appropriate packing boxes. (lifting the box) for the purchaser to pick up. The general suitcase is composed of a box body and a handle. The handle is assembled on the top surface of the box body. After the product is properly packaged into the box body, the handle can be lifted for convenient carrying. The box moves along with the item. At present, there are paper boxes made of recyclable paper materials. However, the "lifting handles" that are matched with them are still made of resin materials, and are generally called "plastic handles".

"Plastic handle" has been used for a long time. In recent years, it has been found that plastic products made of plastic materials have the potential to release toxins and cause serious pollution to the environment. After destruction, it is difficult to recycle and recycle, or recycle. It is difficult to handle, the cost of recycling is huge, etc. - and other industrial pollution problems, so the use of plastic materials is also criticized. Under the circumstance of responding to the trend of environmental protection and reducing the use of plastics, under the circumstance of searching for new materials, it has been developed to use pulp fiber materials and/or plant fiber materials as a slurry material, and to absorb the slurry by suction mold. The manufacturing technology of attaching the slurry and then setting it into a finished product by hot pressing, the finished product made by the manufacturing method is generally called "paper-plastic product", and is clearly distinguished from the paper product or the plastic product.

Even though the manufacturing technology for manufacturing paper-plastic products has been introduced, so far, there has not been a paper-plastic handle. The reason is that the product of "lifting" must have the characteristics of high load resistance. If it can't withstand high load, it may be used to cause surface rupture when lifting heavy objects, or even break the goods in the box, so it is better not to change. . That is to say, since the direct molding of the general paper-making product manufacturing method cannot meet the requirements of high load resistance, no paper-plastic lifting has been introduced.

In view of the need to produce paper-plastic handles, the inventors have carried out innovative research and development in terms of construction and manufacturing methods, and have undergone various changes in construction and adjustment processes, and have been tested by various methods, and finally the present invention has been produced.
