Canned food is mostly packed with metals such as tinplate and aluminum alloy. Its surface is smooth, has high hardness and has an oxide layer. Conventional coding is prone to problems such as insufficient adhesion and peeling. At the same time, can production requires high-temperature sterilization and high-pressure cooking processes, which puts forward strict requirements for the high temperature resistance and corrosion resistance of the logo. Relying on more than 40 years of industrial marking technology accumulation, Zicai has created exclusive high-adhesion coding equipment based on the characteristics of metal packaging of cans. From special ink formulas to optimization of spray printing processes, it fully guarantees that the production date, batch code, traceability information and other logos are in the production cycle and circulation links are clear and complete.
1. Breakthroughs in core technologies: overcoming the problem of metal packaging attachment
Lingxin solves the pain points of metal packaging logo attachment through collaborative innovation of special ink systems and jet printing technology. It adopts high-adhesion pigment ink for metals, and adds special resin and silane coupling agent components. It can penetrate through the oxide layer on the metal surface to form a dual combination of physical anchoring and chemical adsorption. After spray printing, the logo is firmly attached to the metal substrate and can withstand repeated friction and collision. Do not fall off.
For the high-temperature sterilization process of cans, the ink is optimized for high-temperature curing and can withstand high-pressure cooking at 121 ° C for 30 minutes. You can use high-adhesion anti-boiling inks or high-temperature color-changing inks to remind customers that the products have been heated at high temperatures, which is in line with canned food processing process requirements. In terms of jet printing technology, it is equipped with an intelligent inkjet pressure adjustment system to dynamically adjust inkjet parameters according to the surface smoothness of the metal can to ensure uniform adhesion of logos in different positions such as the can body and can bottom. The three-month patented cleaning-free sprinkler is optimized for metal dust prevention, and the special flow channel design reduces blockages caused by metal debris in can production and ensures the stability of continuous production.
2. Exclusive model plan: Match multiple can production scenarios
1. Core of high-speed can production line: Linx 8920
For high-speed production lines of large canning companies such as meat and fruits, the Linx 8920 continuous inkjet printer uses a printing speed of 1500 characters per second to adapt to the production rhythm of hundreds of cans per minute. The equipment supports simultaneous printing of multiple information such as production date, batch code, and traceability QR code. The multi-line typesetting design can completely present compliance information in the limited packaging space of cans.
Equipped with a high-precision positioning sensing system, it can accurately capture the rotation or translation position of the can, realize circular spraying on the can body or fixed point spraying on the can bottom, and avoid mark deviation caused by deviation in the placement of the can. The body is designed with IP55 protection rating, which can withstand steam, water stains and metal dust in the production workshop, and adapt to the production environment of high temperature and high humidity for cans.
2. Preferred for high adhesion of metal cans: Linx 8840 Spectrum
For the production needs of small and medium-sized canning companies, Linx 8840 Spectrum is the preferred choice for its balanced high adhesion performance and adaptability. Support switching of multi-color inks such as metal-specific white ink and red ink, which can form high-contrast marks on the surface of dark metal cans to improve recognition. The printing speed can flexibly match the production rhythm of 200-500 cans per minute and adapt to the alternate production scenarios of multiple specifications cans.
The equipment has a built-in printing template exclusive to the canning industry, which can quickly retrieve common identification formats and parameters and shorten the commissioning time for production change. The intelligent temperature compensation system can automatically adjust inkjet parameters according to changes in workshop temperature, ensuring stable inkjet printing effects in different seasonal production scenarios and strong consistency of logo attachment.
3. No consumables permanent labeling scheme: Linx CSL30
For canning companies pursuing long-term label stability and environmentally friendly production, the Linx CSL30 carbon dioxide laser coder provides a consumption-free solution. The laser beam forms a physically etched mark on the surface of the metal can, which has no risk of ink migration and meets food contact safety standards. The mark can withstand high temperature sterilization and acid and alkali corrosion, achieving permanent traceability.
Laser jet printing does not need to touch the can body, which can avoid incomplete marks caused by slight deformation of the can body during high-speed production. At the same time, it can adapt to special packaging forms such as special-shaped cans and sealed can lids. The identification has high accuracy and can clearly present the traceability code in the format of tiny characters, helping enterprises build a full-chain traceability system and improve quality control capabilities.
3. Industry customization optimization: fit the entire process of can production
For the spray printing needs after sealing cans, the equipment can adjust the angle of the nozzle to adapt to the curved surface of the can body to ensure that the marking on the edge area of the sealing is complete and without breakpoints. In the packaging scene of acidic and oily canned food, special corrosion-resistant inks can prevent the logo from leaking and corroding by the contents and ensure the integrity of the logo.
4. Full-cycle service guarantee: escort compliance production
Leading professional engineers can come to investigate the speed, can type materials and production process of the can production line, and customize accurate model selection and parameter configuration plans for the company. After the equipment is delivered, free installation, debugging and operation training are provided, focusing on explaining the parameter adjustment skills of metal packaging spray printing and the key points of equipment maintenance in high temperature environments to ensure that operators can quickly master core skills.
More than 40 service outlets across the country provide special inspection services to investigate equipment hidden dangers in production in advance. Metal special inks and consumables are guaranteed timely supply through the national unified supply chain to avoid the shortage of consumables affecting production. From equipment selection to after-sales maintenance, full-process service support makes the label management of canning companies more worry-free.
The color can printer takes the high adhesion of metal packaging as its core advantage, and matches the diverse production needs of the can industry through technological innovation and scenario adaptation. Whether it is high-speed large-scale production or small and medium-sized flexible processing, shicai can use professional equipment to help enterprises achieve compliance and stable labeling and ensure the full life cycle traceability of canned food.
