Japan launches vacuum packaging for canned coffee

Japan launched a new vacuum packaging for canned coffee, which consists of a conventional metal can body, a vented cover, a fully-opened end cap, an outer lid, and a bottom of the jar, to reduce the aroma of coffee and prevent the product from being released. Oxidation, the cover of the new packaging cans is made of LLDPE and is sealed on a metal can with a fully open end cap under a pressure of 0.03-0.07 μpa. Deep marks are engraved around the fully open end caps. The pull ring can be opened and turned on very conveniently. The vent cover is vented and the full open end cap is opened to adjust the head space pressure in the tank. Make sure coffee particles do not leak out easily.
