The wooden box in-situ foam packaging method is a kind of shockproof packaging technology in which the product and the outer box prevail, and a foaming material is filled in between. This method is very simple. The main packaging equipment includes containers and spray guns containing isocyanate and polyol resin. When using, firstly adjust the temperature and pressure in the container containing the two materials as required, then The material is mixed and sent to the spray gun with a single pipe and sprayed from the spray head. The ejected compound began to foam and swell in 10 seconds and foamed and expanded to 100 to 140 times its original volume in less than 40 seconds. The resulting foam was polyurethane and became hard and one minute later. Semi-rigid foam. These foams will wrap around in any shape of item. For products with good integrity and products with internal packaging (eg, cartons), use cushioning materials only at the corners or areas of the product or inner packaging. This method is called partial shockproof packaging. The shockproof materials used are mainly foamed plastic shockproof pads, inflatable plastic film shockproof pads, Polaroid and rubber springs. In the actual buffer packaging, two or more shockproof methods are often used in combination. For example, both padding and amorphous cushioning materials are added to make the product more fully protected. Improve the operation speed of wooden box packaging machinery, the quality of wooden box packaging, reduce waste and various kinds of wear, meet the needs of wooden box packaging for bulk products, reduce operating costs, adapt to the requirements of seasonal and timely wooden box packaging, and improve wooden box packaging machinery products. The serialization, standardization and generalization level, the acceleration of the upgrading of equipment, and the establishment of a structural system of modular or modular modern wooden box packaging machinery are an important development direction in the future; the development of the wooden box packaging industry is promoting the food industry. To improve and improve people’s living standards,

Its main material is diatomaceous earth.Its main characteristic is super super super absorbent,which can instantly absorb water from your feet and non-slip.It is also all-natural and can absorb harmful chemicals from the air 24 hours a day.What's more, it's easy to clean up and can be customized.
The main constituent of diatom mud is diatomite,The diatom has numerous tiny pores on the surface of the microscope.It has up to 90% porosity surface that absorbs excess moisture quickly.And can absorb water 2-4 times its own weight.
Molecular sieve structure of diatomite.The surface area is 5000-6000 times that of activated carbon,make it physically absorbing and particle exchange.and remove harmful substances such as formaldehyde, benzene, and ammonia in the air.Converted into harmless substances by absorption decomposition.Thus functioning as a net taste
