1 Aluminum foil yana da farin farin azurfa, aikin bakin ciki da haske

Aluminum foil yana da farin fari mai haske mai haske, wanda ba shi da guba, m, kuma mara lahani ga jikin mutum. Bayan yin launi, embossing da bugu, yana iya samun kowane nau'i mai launi da alamu ba tare da rasa kyakkyawan haske ba. A halin yanzu, ƙaramin kauri na birgima na iya kaiwa 4pm, kuma akwatin aluminum yana da haske, kamar foil aluminum mai kauri na 6um, wanda nauyinsa kawai 16g a kowace murabba'in mita.

2 Ayyukan ƙwaƙƙwaran ɗanshi na foil aluminum

Idan aka kwatanta da sauran kayan marufi, aluminum tsare yana da low danshi permeability, kyakkyawan aikin tabbatar da danshi, kuma yana da fa'idodin aminci, saukakawa da kuma tsawon rai, ko da yake pinholes da Kamar yadda kauri na aluminum foil rage, Ayyukanta na tabbatar da danshi har yanzu yana da fa'ida akan fina-finai na filastik ba tare da ramuka da sauran kayan tattarawa ba, because the polymer chains of plastic have a large distance from each other and cannot prevent water vapor from penetrating. If the surface of the aluminum foil is coated with resin or compounded with paper or plastic film, its moisture-proof performance is better. See Table 2-1 for the moisture permeability of aluminum boxes and plastic films with different thicknesses.

Tebur 2-1 Moisture permeability of aluminum foil and plastic film

The thickness of aluminum foil is so small that pinholes inevitably appear to a certain extent, and the minimum thickness of pinholes is generally considered to be 0.038mm. 025mm。 Due to the improvement of rolling technology and material, an rage wannan kaurin zuwa 0. 025mm. Hakanan an tabbatar ta hanyar gwaje-gwajen cewa diamita na ramin iska yana da mahimmanci. Lokacin da diamita bai wuce 5um ba, ba za a iya watsa iskar oxygen da tururin ruwa a cikin kewayon da za a iya aunawa.
