The sack generally contains green coffee beans, which can be stored for one year in a dry one, while the roasted coffee beans can be oxidized when placed in a sack, and the smell will disappear after a long time. The roasted coffee beans are generally packaged with a one-way exhaust valve: the roasted coffee is placed in a special one-way exhaust valve. This exhaust valve allows gas to go out, but not in. There is no need for a separate storage stage, but due to the outgassing process, the fragrance will be slightly lost. It avoids the formation of spoilage taste, but cannot prevent the loss of aroma.
Moisture protection for Coffee Beans
1) Moisture-proof Coffee beans will accelerate their moisture rate after being damp.
2) Anti-oxidation The oil and aroma components in coffee beans are easily oxidized when exposed to oxygen.
3) Gas barrier. Ordinary coffee beans are prone to loss of volatile aromatic components and are easily affected by peculiar smells. Therefore, the packaging of ordinary coffee must avoid spilling aromatic gases from the packaging and absorbing odors from the outside. Therefore, packaging materials should have sufficient gas barrier properties.
4) Anti-high temperature Under high temperature conditions, the biochemical reaction and volatilization speed of coffee will be accelerated.
[Protection requirements for coffee beans]
Loading, unloading and handling links--As the packages are transported in corrugated cartons, generally speaking, the longer the process, the more transfer links and the more loading, unloading and handling times. When designing the packaging and decoration of corrugated boxes, if there are eye-catching handling signs on the packaging, smooth surface, reasonable hand holes or handles, necessary strapping, and packaging weight and external dimensions that conform to human factors, it can be effectively Reduce the occurrence of rough handling.
[Transportation link]-Long-distance transportation uses cars, trains, ships and planes, and short-distance transportation mainly includes forklifts, battery trailers and trolleys. This design is to use long-distance transportation vehicles. The reasons for the damage to the package of goods during transportation are: impact. The starting, shifting, steering, and braking of the means of transport will change the speed of the cargo.
The shock of the package mainly occurs in the process of loading and unloading and transportation, and can be divided into horizontal shock and vertical shock. Vertical shock is mainly caused by falling during handling, loading and unloading, and lifting. Horizontal shocks mainly occur when transport vehicles are driving on rugged and uneven roads, when vehicles suddenly start or brake, when airplanes are landing, and when ships are docking.
Climatic conditions. Long-distance transportation of goods has to go through different climatic regions, and is affected by climatic factors such as cold, hot, dry, humid, wind and rain. If the packaging structure of the goods is improper, the material is improperly selected, and the sealing is not strict, the contents may deteriorate or be damaged.
[Other factors] Specifically, oxygen, carbon monoxide, carbon dioxide, hydrogen sulfide and other gases, as well as salt fog, rain, heat sources, radioactive sources, odor sources, sunlight exposure, etc. will accelerate the degradation of the quality of packaging and contents, pollution or Damaged. [1] Electronic products should consider the impact of environmental electric fields on their performance. Valuables should also consider the problem of tamper-proofing.
[Storage Links]-Goods storage method, stacking weight, height, storage period, storage location, storage environment, etc. directly affect the circulation safety of product packages. The architectural structure of the warehouse has a great influence on factors such as temperature, humidity, and air pressure in the storage environment.
Therefore, the stacking pressure strength of packaging containers must be checked during design to ensure the safety of goods during transportation and storage. In addition, as far as the contents are concerned, the space enclosed by the packaging is a kind of miniature environmental condition. In order to implement the protective function, packaging parts are often composed of containers, structural materials, gasket materials, inner coatings, adhesives, sealing fillers, printing inks, etc. They often have certain chemical properties and come into contact with the product. If they are not handled properly, they will contaminate the product inside and cause the product to taste bad. Therefore, the compatibility of packaging and its materials with the packaged products should also be valued by packaging designers and manufacturers.
