We often see all kinds of coffee bags in the supermarket, so what are the requirements for the packaging of coffee bags in the production process?It is easy to lose the volatile aromatic components and is susceptible to odor.Therefore, for ordinary coffee packaging, it is necessary to avoid the aromatic gases from the packaging and absorb odors from the outside.Packaging materials must have certain barrier gas performance.
1. The moisture-proof coffee will speed up the tide after the damp.
2. Oxidation of oil and aromatic ingredients in antioxidant coffee.
3. Instant coffee should also be paid attention to moisture-proof and anti-oxidation.
4. The high temperature will speed up the biochemical reaction and volatilization rate of coffee.
At present, almost all regular coffee USES air-tight vacuum packaging technology or inflatable packaging technology.Vacuum packaging technology is the coffee bagging, vacuum and seal.The filling technique is to vacuum and fill in other inert gases before sealing.The inflatable pack of coffee is often filled with nitrogen or carbon dioxide.Both types of packaging are designed to eliminate oxygen.Therefore, the packaging materials used must have certain air tightness and heat sealing performance.Vacuum and aeration packaging technology can effectively prevent the oxidation and moisture of coffee.
