Analysis of the reasons why printing machinery nozzles do not emit ink
Aluminium foils are used to wrap food items because aluminium being a soft malleable metal it can be beaten to in sheets to form thin wrapping sheets. Moreover it does not react with food items. Immersion rods are made of metallic substances metals are good conductors of heat and electricity.
Increasingly, aluminum foil is being merged with flexible films to create lightweight packages. This technology allows the packages to expand during production, then contract as the product is consumed. The packaging of pet food, tuna, coffee and soups alone produces 13 billion packages that are candidates for replacement with flexible foil-based packages.
Aluminum foil provides a complete barrier to light, oxygen, moisture and bacteria. For this reason, foil is used extensively in food and pharmaceutical packaging.
Benefits of Aluminum foil when packaging food
Aluminum packaging is light, flexible and easily recyclable. Furthermore, it is hygienic, non-toxic and helps in keeping the aroma of foods. It keeps the food fresh for a long time and provides protection from light, ultraviolet radiation, oils and grease, water vapour, oxygen and microorganisms.
In addition, have a look at the following advantages:
ï¬Aluminum foil reacts only to highly concentrated acids and basic substances and is otherwise strongly corrosive resistant
ï¬Aluminum foil is sterile and therefore hygienic
ï¬Aluminum foil is tasteless and odorless
ï¬Aluminum foil is extremely dimensionally stable even in soft state
ï¬Aluminum foil can be recycled several times without loss of quality
ï¬Aluminum foil does not absorb liquids
Despite the contrary claims, aluminum foil in food packaging is generally harmless to health. Acid or salty foods should not come into direct contact with aluminium, but composite films with aluminum layer can be used.
Aluminum foils and laminates are ideally suited for the production of packaging, depending on their thickness, aluminum foils and laminates are used for a wide range of food packaging.

1. The ink is easy to volatilize, volatilizes out solid matter, and some ink remains in the surrounding area, which is easy to clean outside the nozzle hole. This is why we often clean the nozzle.
2, the piezoelectric crystal is damaged, it may be normal for the factory with a lot of inkjet work to be used for less than one year.
3. The fatigue damage of the piezoelectric crystal is obvious when the amount of ink is large. At this time, the nozzle needs to be replaced.
4. The ink does not flow in the nozzle for a long time, and the cross-sectional area of ​​the ink flow becomes small, which also causes the nozzle to not emit ink.
5. The failure of the drive circuit may affect the voltage of the drive head, causing the nozzle to not discharge ink.
6, frequent replacement of ink, will affect the inkjet state of the nozzle.
7, the machine uses the ambient temperature and humidity, the high and low temperature affects the viscosity of the ink, often mistaken for "nozzle blockage."
