Packing Specification:
1.Without plywood case: tinfoil vacuum + bubble wrap + composite kraft paper
2.With plywood case: tinfoil vacuum + carton box + plywood case
Shelf Life of Product:
1 year
Preparation Before Laminating:
1. Clean and fully dry the glass, there should be no particle dust or oil on the glass surface, EVA film and other intermediate materials are spare.
2. After opening the furnace, cool down for 3~5 minutes, until the vacuum value reaches -0.095MPa, close the furnace door and officially heat.

The above temperature refers to the glass surface temperature. The above parameter settings are for reference only, and the specific parameters should be adjusted according to the laminating equipment, temperature, humidity, glass thickness and intermediate layer material.
1.High flow film and low flow film, which one is better?
We can not judge which one is better, they have their own advantages and disadvantages,it is based on your requirement.
2.What determines the film melted index?
Usually, its raw material determines its melted index.
3.Do you offer guarantee for the products?
Yes, generally, we offer 10 years warranty for processing glass based on your normally uses, we advise you uses in a right way can keep your products service life in a long time (more than 5 years).
4.How do you control the quality of your products?
We have standard management on factory based on ISO system, and train our staffs regularly, our production department they will choose high quality materials for glass strictly, for finished excellent products. And we have QC for each process, once find little problem, we will replace the glass, to make sure every piece glass go to warehouse is in good condition.
5.Do you also sell the green tape? How much of it?
Yes, we sell it.The price is based on its size.
