[Abstract]:
look at the certificate: regular manufacturers have the relevant departments of the test certificate and product quality

Due to the rise of the domestic aluminum foil industry in the domestic market, no unified industry norms and standards have been formed. In the market, there is a mixture of fish and dragons, and some manufacturers and wholesalers are trying to make profits, shoddy, paper-based foils, short-cuts, and cut corners. Therefore, consumers should not be confused by the appearance or weight when purchasing aluminum foil paper. You can purchase it by referring to the following methods:

A. Look at the shape: The formal manufacturer's packaging is generally professionally designed, with registered trademarks, factory name, contact telephone number, precautions and usage methods, etc., and marked with length or weight, the packaging is more exquisite and generous. Inferior products do not have these elements.

B. Look at the internal quality: the products of the regular manufacturers can open to view the internal quality, the following points should be noted when opening the box:

1 Look at the color: high-quality aluminum foil paper is like a mirror, the reverse is foggy but the silver is fresh. The surface of inferior aluminum foil is dim.

2 Look at the deterioration or not: Open the seal and pull out 30cm or more to see if there is oxidative deterioration. After the metamorphic aluminum foil is oxidized, white-green alumina will be formed, because the surface of the first circle cannot be distinguished by deterioration.

3 look at the core: regular products will not do paper articles, but from the perspective of saving paper and transportation costs, the inner core tube diameter is generally between 3.5-4.5cm, the inner core wall thickness 1 Between -4mm, and the inferior product inner core tube is made thick and large, in order to replace the weight of the aluminum foil with the weight of the paper tube.

4 See if it is sufficient: The number of turns from the aluminum foil roll can basically distinguish whether it is sufficient. If the visual inspection is not sure, the weight of the inner core tube can be removed by using the electronic scale to distinguish it.

5 look at the certificate: regular manufacturers have the relevant departments of the test certificate and product quality certification, and the general three no products can not be provided, the most effective way to check the authenticity of the certificate is online inquiry.
