In order to achieve energy-saving effects, European and American countries will use insulation panels (VIP panels) in freezers, which can save 30-40% energy.

The vacuum bag used for the VIP insulation board is a very important part of this, and this bag must have the following points:

1) The barrier is very high, and the water and oxygen resistance must be below 0.05 or even lower, because this type of insulation board requires a vacuum state guarantee of 20 years;

2) Because insulation is required, the thermal conductivity must be very low, even close to zero, in order to ensure that the cooling capacity is not lost;

3) Must have a certain level of puncture resistance;

4) Under high temperature and humidity testing conditions, the barrier performance is stable, the thermal conductivity is stable, and the material will not delaminate;

The world's leading VIP board packaging technology is mainly Israel's Hanita Company and Japan's Kuraray Company. Through our efforts, we have achieved moisture and oxygen resistance below 0.05, or even lower, and the thermal conductivity is also very low, so we have met the requirements of European and American countries for high standard VIP board packaging.
