The Classification and Application of Food Packing

Food packaging, is part of the food products. One of the main engineering in the process of food industry. It protect the food, made the food in the process of leaving factories to hands of customers, to prevent biological, chemical, and physical external factors of the damage, It can also have the function of keep food itself stable quality, it is convenient for people to eat the food, also it is firstly present the food appearence, the image to attract consumption, with the value beyond material cost. Therefore, food packing process is an inseparable part of the food manufacturing systems engineering. But food packging process versatility and it has a relatively independent system of self.

The process of using plastic food packaging products mainly include four industrial sectors: the first industry refers to the plastic resin and film production. The second industry is the flexible and rigid packaging materials processing industry, the third is the packaging mechanization production industry, the fourth is the food processing industry. In the first industry is the use of such as oil, coal, natural gas, raw material, synthetic polymerization of low molecular compounds, and then aggregated into various resin. The processed into single or multi-layer composite membrane, for the food processing factory packaging.
Food packaging according to the packing materials can be divided into metal, glass, paper, plastic, composite materials, etc.; According to the packing type is divided into cans, bottles, bags, bag, box, box, etc.; According to the packing way is divided into jar hidden, bottled, envelope, bags, wrapping package and perfusion, the whole set, sealing, labeling, printing, etc.; According to the product level is divided into the inner packing, secondary packaging, three-level packaging... the outer packing, etc.
Because more and more attention to food safety, higher requirements for some countries to strengthen the regulatory management more of the food packaging products. From a nutritional standards regulations, such as the indirect additive regulations to push biodegradable packaging, electronic scanning bar code, etc., promote the new development of food packaging.

Rigid PVC sheet - Metalized Film Grade

Our metalized rigid PVC films are coated with a thin layer of aluminum utilizing the process known as physical vapor deposition. The deposited aluminum is usually 1 micron thick and produces a glossy reflective silver metallic appearance similar to aluminum foil on one side. Our base material is usually ordered in a tinted color and this allows for a glossy metallic colored look on the opposite side taking on the color of the tinted material.

Metalized films have a similar appearance to aluminum foil in their reflective silver surface. The metallic coating also reduces the permeability of the film to light, water and oxygen. The properties of the film remain, such as higher toughness, the ability to be heat sealed, and a lower density at a lower cost than an aluminum foil. This gives metalized films some advantages over aluminum foil and aluminum foil laminates.

Metalized films were first used for decorative purposes as Christmas tinsel, and continue to be used for items such as wrappers and ribbons. Many food items are also packaged using metalized films for appearance. These produce a package with greater sparkle when compared to competing products that use printed paper or polymer films.

The Proper Methods of Removing Adhesive Sticker Cleverly

The adhesive sticker label is also called the self-adhesive label materials, on paper, film or special material for the fabric, coated with adhesive on the back, a kind of composite materials with silicone-coated protective paper as the bottom paper. After the adhesive printing labels use, some hard surface are often left with traces of viscosity, both affect beautiful and difficult to remove, let us introduce the removing methods below.
1. First with the blade or the ink shovel to remove the sticker surface materials, with gasoline or acetone to remove residual glue, cloth with gasoline or acetone, wipe the residue adhesive is ok. Gasoline, acetone are good organic solvents, can dissolve the adhesive sticker label glue.
2. Heating can make double-sided adhesive glue bate: With blower to soften the glue, when the double-sided adhesive stick force, can be more easily removed. If there is a little trace, with clear nail polish to light the water to wipe.

3. A little ammonia water added with soap and a mixture of turpentine oil, can remove a lot of dirt and the glass surface more luster (this article is suitable for ceramic tile, ceramic, glass, etc.).
4. If the area of the self adhesive label is not too big can dip in with cotton wipe nail polish remover.
5. Dip in with dishcloth wiped with essential balm, later have tags to won't leave traces.
6. The use of special cleaner or sneakers wipe decontamination creams.
7. Take a piece of dry cloth dipped in vinegar, to cover the entire place of two-side glue trace, after wait for double-sided adhesive glue stains completely wet, can be easily eliminated with your ruler.
Finally, at the time of cleaning, is whether to use soap or vinegar, must let these supplies completely soaked two-sided glue mark, will be able to easily remove adhesive stickers.

Glass drilling machine use method and matters needing attention

Application method
1. When drilling glass, the drill bit was easy to crush the glass, so when drill the thin glass, pressure must be very low, only within the range of 0.18 ~ 3 mpa, when drill the thickness glass, pressure can be up to 0.46 MPa.
2. Before the start of glass machinery per shift, to the oil injection parts should be inject the lubricating oil, and check the belt tightness, if top and bottom drill shaft operation is abnormal, whether the drill bit wear and tear, after everything is ok may be start to work.
3. The drawer of the core material should be cleaned up in time, otherwise the core material pile too much will get stuck the picking device. Especially the big hole drilling diameter greater than 100 mm, each drill a few holes you should clean up one more time.
4. Clean up the core material should make the picking device in the connect material position, so that material drawer can smoothly draw out, so when clear the core material to bit on start to spin, this moment the picking device is in the material position, can easily clean up core material.

Matters Need Attention
1. Pay attention to safety when using, when the glass drilling machines starts not to touch the movement parts and electric parts;
2. Tools and other items do not put in conveying guide rail and hood;
3. When there is an emergency, immediately press the emergency "stop" button or pull air switch;
4. Keep the water tank adequate of cooling water, clean water quality at any time, in order to avoid burning grinding wheels and glass, and timely clear the grinding impurities in and out of the water pipes, keep the waterways clear.
5. Each class should check if all the travel switch is normally work and the control direction is correct before grinding work, if not, directional control is not correct, it is necessary to stop the drilling machine immediately to check, otherwise the machine will have fatal damage;
6. The motor temperature: less than or equal to + 50 ℃ ambient temperature.

The particular Qualities and Features of Retort Pouch

Retort pouch is made of a flexible type of metal plastic laminate which is capable to withstand thermal processing for sterilization. Foodis first prepared, even raw or cooked, and sealed to the retort pouch. The pouch will be heated to 240-250°F (116- 121°C) for a few moments under underhand, inside retort or autoclave machines. The foodstuff inside is cooked, just like pressure cooking. This process reliably kills all commonly occurring microorganisms (particularly Clostridium botulinum), preventing it from spoiling. The packaging process is very much like canning, with the exception that the package itself is flexible. The lamination structure doesn't allow permeation of gases externally into the pouch. The retort pouch construction varies from application to application, to be a liquid product needs different barrier properties when compared to a dry product, similarly an acidic product needs different chemical resistance compared to a basic product. Some different plastic layers employed in retort pouches:
* Polyester PET offers a gloss and rigid layer, may be printed inside.
* Nylon Bi Oriented Polyamide, provides puncture resistance.
* Aluminum Al Provides a very thin but effective gas barrier.
* Food-grade cast polypropylene or CPP is needed because the sealing layer.
* Polyethylene (PE) can be used as an alternative to PP as being a sealing and bonding layer.

This multi layer structure prevents the retort pouch from being recycled into other retort pouches or food packaging. However this fabric can be recycled into an aluminized resin or up cycled into textile materials. The load of any pouch is lighter than regular cans or bottles, plus the energy necessary to produce each pouch is a lot less than competing packaging from metals, paper, and glass.
Microwavable Pouch/Film
To reduce consumer inconvenience, the microwavable pouch has a computerized opening system during the microwave process. You don't have to go out of open any kind in the microwavable pouch/film before heating in the microwave. The microwavable retort pouch/film will quickly self vent inside the microwave in the event the food, packed from the microwavable retort pouch/film, is put within the microwave and starts to warm up.
The microwavable self-venting feature is given to the retort and pasteurization products.
The microwavable pouch/film has undergone matt treatment for appearance and offer high barrier features.

The purpose and classification of welding

Welding, is a kind of joint in the form of heat, high temperature or high pressure metal or other thermoplastic materials such as plastic manufacturing process and technology. Welding is to use all kinds of fusible alloy (solder) join the process of metal parts. Soldering tin melting point is lower than the welding materials, this part will be in the case of not been melted, through its end welding equipment surface contact between the molecules.

Welding through the following three ways to realize the purpose of the joint:
1. The heating to joint the workpiece to form the partial melting of molten pool, pool and joint after cooling solidification, can melt filling material by adding auxiliary when necessary;
2. Separate heating with low melting point solder, without melting the artifact itself, by capillary action of solder connection artifacts (e.g., soft soldering, brazing);
3. In an equal to or lower than the melting point of workpiece temperature with high pressure, composite extrusion or vibration make the mutual infiltration between the two artifacts joint (e.g., forge welding, solid-state welding).
With leading domestic high power optical fiber transmission technology, projection welding machine equipment performance close to the international similar products level, can implement transfer spectral processing; Germany of imported optical fiber, has a stable energy, low fiber loss, large processing depth to diameter ratio, etc; And optional, implementation of special welding robot and online production.
Welding can be divided into soft and hard, soft soldering temperature below 450 ℃, brazing is higher than 450 ℃. Hard welding is usually used in silver, gold, steel, copper and other metals, the welding point is more strength than soft welding, shear strength of soft welding 20-30 times. The above two kinds of thermal coupling are usually use the term welding spot welding machine, because in the two cases are the molten solder written to two device for cleaning and approached in the narrow gap on the surface of the solid metal.
