A must-have for staying up late at work - coffee, its taste and its raw materials can refresh and invigorate the spirit.
As one of the common beverages in life and work, we often use instant coffee, which is usually packed in bags or cans.
It is further divided into: non-airtight packaging, vacuum packaging, one-way valve packaging, and pressurized packaging.Non-airtight packaging is actually a temporary packaging, only used for short-term storage; vacuum packaging requires roasted coffee beans to be placed for a period of time before packaging to prevent carbon dioxide from damaging the packaging. This type of packaging can generally be stored for about 10 weeks.

Testing equipment: HP development seriesAir tightness detector
Detection method: Use negative pressure and indirect detection methods, combined with customized molds and tooling.
Exhaust air to -10Kpa, time is 8s, stabilize pressure for 8s, test for 5s, and quantitative air intake for 4s.During this process, if the leakage exceeds the upper limit of 50pa, the program triggers an alarm or an NG signal appears, that is, the sealing of the jar is unqualified and it is a defective product.
