Eoe neck folding refers to the existence of different degrees of folding phenomenon (usually slight) in the neck of empty cans after the neck of cans. The crease of the neck of the can only affects the appearance of the product and does not involve the double roll sealing.There are three causes for the crinkling of the neck of a can. One, can neck metal circumference thickness is not completely uniform. Secondly, in the production process, the expansion of the neck die due to the temperature rise will lead to a slight change in the internal and external die clearance. Because the matching of raw materials and mold space is not fixed, when the fluctuation of matching exceeds a certain degree, the metal in the neck may produce wrinkles in the process of extrusion. Third, occasionally there may be slag, light oil particles and other foreign bodies on the outer wall of the neck of the tank, resulting in neck constriction folds.Although the neck fold problem is difficult to completely eliminate, but the degree is generally not too serious, often the number is very small. There has never been a consumer complaint about the return precedent, so customers can directly use. Of course, if a large number of such problems are abnormal, need to be analyzed and solved.The washing and disinfection of tinplate can can be divided into manual and mechanical cleaning. Manual cleaning refers to washing with hot water, disinfection in boiling water for 30-60 seconds, then drain water upside down. Artificial cleaning is a disadvantage: labor intensity, low efficiency. Mechanical cleaning is hot water washing, boiling water or steam disinfection 30-60 seconds, its advantages are automatic, washing quantity is high, high efficiency.

Eoe quality of the basic requirements, should be sealed and eoe. In the past, many people often used pliers to help them open the tin lid. Sometimes when the rivets fell off, they could only still use a tin opener. Special-shaped cans are more difficult to pull open the lid.And the production of tinplate eoe equipment are mostly imported products, the relative price and maintenance and after-sales service costs will be relatively high, in fact, mainly the use of tinplate thickness, hardness and mold problems. And now our domestic enterprise organization technical force, carefully study easy to pull cover equipment production line, the use of effective measures, constantly improve the quality, give play to the advantages of easy to pull cover and due role.Eoe quality of the basic requirements, should be sealed and easy to pull.Eoe lid, also called eoe lid, is used to seal cans with a pull lid, belongs to the metal packaging products. Made of aluminum or tinplate, with various sizes, suitable for iron cans, aluminum cans, composite cans, PET plastic cans and paper cans, etc. (Eoe equipment)Easy-pull lid is the lid used for metal cans in food canning industry. Easy to pull cover process: iron sheet a foundation cover forming → pull ring combination forming → post-processing process → imaging visual detection → cover packaging. Easy to pull cover circular and non-circular two categories, irregular easy to pull cover refers to the non-circular easy to pull cover, such as oval, square, horseshoe, etc. Easy pull lid is used for sealing and opening cans, its definition is pre-engraved with a certain depth of the notch line and riveted pull ring opened along the notch line can be safely torn cover. It is a better anti-counterfeit bottle cap. Easy to pull cover is more difficult, and many enterprises have fully considered the need for anti-counterfeiting before use, so the design of poor interchangeability is used when making the cover. The universal type is not good, so it has a certain anti-counterfeiting effect. Another anti-counterfeiting effect of easy-pull lid is that special equipment is required when using it, so the use of easy-pull lid wine products is less counterfeit.

Eoe two cans are mainly used for carbonated drinks and beer packaging. At present two - piece cans are mainly aluminum two - piece cans. The aluminum two-piece tank is made of thin aluminum alloy. The thinning and stretching process is used in the manufacturing process, so the thickness of the tank wall is significantly thinner than the tank bottom. When used for beer packaging, the strong internal pressure compensates for the rigidity of thin cans. But the high air resistance, shading and sealing of metal cans will keep the quality of beer in cans stable. These metallic characteristics allow the canisters to be filled at constant pressure or at high speed.Two cans have a good seal. The tank body is directly formed by drawing process without leakage. The two cans do not need to be welded and sealed, to avoid lead pollution from the tin, and high temperature sterilization, to ensure product health. The body of two cans has no seam, beautiful shape, and the body can be decorated and printed continuously, and the effect is good. Two cans only have two parts, and the tank body manufacturing process is simple, with the benefit of increasing production capacity. The tank body of two cans is formed as a whole, without longitudinal seam of the tank body and joint with the tank bottom, which also saves materials.The main function of easy-pull lid can sealant is to seal in the double edge of easy-pull lid can. During loading, unloading, storage and transportation of cans, the contents of cans can be protected. And the performance of sealant, sealant should control the dry film amount, oil resistance and water resistance of sealant. The correct location distribution of the hook edge inner film is: about 70% inside the hook edge and about 30% in the plane. In addition, the size of the film should meet its own process requirements. Excessive amount of glue is easy to cause extrusion, especially in the case of metal can materials are becoming thinner and harder, the dry film amount of easy to open sealant should be appropriately decreased. At the same time, it should be noted that the amount of sealing film to achieve the sealing effect plays a decisive role in the volume of the film, so it should be clear about the density of the sealant on the easy to open cover, and then determine the amount of dry film of the sealant on the easy to open cover of various varieties.

The supermarket is full of goods, all kinds of packaging, have a plenty of eoe, have a plenty of hot sealing, have a plenty of aluminum foil sealing..... Which way of packing is better? What difference does it make? Let's analyze it:Where are the different types of Elaget used? Below by the technical professional easy to pull cover manufacturers to give you interpretation:Eoe is divided into aluminum easy to pull cover, ma Kou iron eoe, drinks eoe, aluminum and platinum eoe.Aluminum eoe lid is generally used in nuts, powders, snacks and other packaged foods.Ma Kou tieyi pull lid is generally used in canned packaging (such as: canned fish fruit, canned meat food fruit, canned vegetables and fruits).Beverage eoe is plainly applied in a variety of health drinks packaging (such as: wine, fruit juice, carbonated drinks).Aluminum-platinum removable lid is used in powder, dry goods knowledge (such as: baby milk powder, instant coffee, seasonings), etc.We can choose suitable eoe according to unnecessary goods.What is the difference between eoe seal and aluminum platinum seal?Eoe seal and aluminum platinum seal is not the same machine equipment.Aluminum-platinum sealing is carried out by induction aluminum foil sealing machine, there are two methods of water cooling and air cooling, water cooling heat dissipation sealing is mostly pneumatic, can be used to day appliances, paper balls and other industrial supplies plastic film packaging seal. Therefore, the automatic sealing machine is also known as pneumatic automatic sealing machine.Eoe the lid seal is the lock cover machine. There are automatic sealing, automatic sealing, automatic sealing difference.The above is a simple classification of packaging, I hope to help you.
