12OZ Coffee Packaging Pouch Matt Flat Bottom Printed With Tin Tie

Description:

Our flat bottom coffee bag has two addtional highlights: one-way degrassing valve and tine tie. For odour retentive coffee bags, it needs a one-way degassing valve which helps to remove excess gas inside the bag produced by freshly roasted coffee. The working principle of the degassing valve is that when the gas generated by the items sealed in the bag reaches a certain pressure, the gas can be pushed from the inside to the outside to open the degassing valve sheet, and the excess gas is discharged outward. The valve closes automatically when the pressure reduces to a level that cannot open the valve sheet.The valve will automatically open only when the pressure inside the bag is higher than the pressure outside the bag otherwise, it will not open, therefore the external air cannot enter the bag. It is needless to say One way degassing valves are extremely important to be used with products that produce gas after being packed.

While coffee may be a shelf-stable product and can be safe to consume after its sell-by date, it will degrade in quality over time. For customers to enjoy a coffee’s origins, complex aromas, and flavours, roasters must ensure it is packaged and stored effectively in order to protect these characteristics. Coffee is known to contain over 1,000 chemical compounds that contribute to its taste and aroma. Processes such as gas diffusion or oxidation during storage can lead coffee to lose some of these compounds. This, in turn, often leads to a decrease in consumer enjoyment. Notably, investing in the right packaging materials can help protect a coffee’s characteristics. However, the way in which the packaging is made resealable is just as important. Tin ties and zippers are two of the most affordable, accessible, and easy-to-use ways roasters can seal coffee bags or pouches. That said, they do not perform the same way when it comes to preserving coffee freshness.ZRPACK can apply both tin ties and zippers.Tine ties is twist tiie, which can preserve the coffee or other product's freshness. Its was done using a thin length of covered wire. This wire could be fastened around the end of a packet and re-tied whenever the bag was opened.
