The global low-carbon environmental protection storm has spread to the packaging field, and the concept of low-carbon packaging has been proposed. The main content of low-carbon packaging includes lightweight packaging, cleaner production, green products, energy saving and emission reduction, and paper-based wood. Paper-based wood is the core of low-carbon packaging. The recycling of waste paper not only reduces the amount of wood, cuts less trees, protects the ecological environment, but also saves energy and water, and reduces emissions. According to calculations, the use of waste paper to produce 1 ton of paper can save 5 cubic meters of wood, 60 cubic meters of water, and 300 kilowatt-hours. A new approach to “containerless packaging”. All kinds of goods, where you only need to protect the corners and don't need to be inclusive, benefit greatly from them and are more energy-saving and environmentally friendly.

 

       Paper corner protectors are products that can be customized according to customers, so there are many specifications. There are three main types of paper corner protectors.

 

　　L-shaped bending paper corner:

 

　　L-shaped paper corner protection is made of sand tube paper kraft paper through the corner protection machine pressing and bonding. The corner protection angle is 90°. The side length can be made equilateral or unequal, for example: 1000* 40*60*5mm is a unequal side specification. The size range of the corner protector is relatively large, and the length can be cut. Generally, the normal range is 100mm-3000mm. It can also be adjusted according to customer requirements. The width range is between 30mm-100mm and the thickness range is between 2.5mm-8mm. Provide additional printing, according to customer requirements to print the required patterns, the color is generally cattle card color, or according to customer requirements, white paper on the surface, the appearance is more beautiful.

 

　　Torx buckle paper protector angle , 90 degree paper protector angle, Torx buckle paper angle protector, 90° paper protector angle requires additional molds to be punched out according to different shapes. The specifications can also be customized according to customer requirements, and the side length can also be unequal-sided. Due to the limitation of the mold, the width is generally not less than 40mm, and the thickness should not be too thick. Normally it is 3-5mm. If it is too thick, it is easy to bend and buckle. When surface burst occurs, it is mainly used for wrapping corners to protect the corners of the product from damage.

 

　　U-shaped paper corner protectors. U-shaped paper corner protectors are less used. They need to be made and punched out from the upper die. They are generally used in conjunction with honeycomb panels. They are mainly used for packaging in the glass, lighting, and furniture industries.
