1.How should I store packed sheets?

Store in a protected, shaded, ventilated site, with no direct exposure to sunlight and winds.
In outdoor temporary storage cover with opaque protective film, and avoid PVC films and heat-absorbing materials.
Please note: Surface protective films that cover sheets are highly sensitive to heat and direct sunlight. Excessive heat and direct sunlight before taking off the film can cause gluing of that film to the sheet surface, after which it will not be practically possible to remove it from the sheet!

6.Comparing with ABS,PMMA,Glass, what is the advantage of PC sheet?

The Bending strength of ABS sheet is weak, The Mechanical properties are greatly affected by temperature, with Poor weatherability.. Under the action of ultraviolet light, it can be degradation. Additionally, it can be burning with fire.

For PMMA, The life expectancy can be maximum 5 years when using outdoor. The heat distortion will be 100 centigrades, with poor impact-resistance.

For the Glass, the weight is heavy, it will be as much as 12 time for the same thickness of PC solid sheet.

For PC solid sheet, it has high impact-resistance and good weather resistance. The weight only can be 1/12 as Glass.

The life expectancy can be as much as 10 years, depending on professional installation practice and environmental factors like air pollution, winds and rain.
