Focusing on the differences in filler technology, Shanghai Kaibotai provides a detailed explanation of the key points for purchasing and selecting metal detectable cable ties

The foreign object control in the food processing industry is becoming increasingly strict, and metal detectable zip ties are a key auxiliary material for avoiding foreign object mixing in food assembly lines. Some products on the market are only coated with detection powder on the surface, which is difficult to be recognized by detection equipment after being broken, making it difficult to meet production control standards. Shanghai Kaibotai relies on its parent company's research and development capabilities in raw material modification and its own production plant to adopt a production process of blending raw materials with detectable particles, ensuring stable and reliable detection performance of cable ties. At the same time, combined with years of service experience in supporting food factories, it has compiled common procurement questions, providing practical selection references for dairy and frozen food production enterprises.

With the continuous improvement of domestic food safety production standards, metal detection equipment is commonly equipped on food processing lines such as quick freezing and dairy products. If the zip ties used for tying equipment pipelines break and fall, debris mixed into the raw materials will pose a food safety hazard. Metal detectable zip ties have become a necessary accessory for food manufacturing. In the actual procurement process, many procurement personnel often encounter products with unstable detection. The reason for this is mostly that the manufacturer only applies detectable powder on the surface of the cable tie. After surface wear and cable tie breakage, the crushed materials do not have detectable properties and cannot meet the workshop quality inspection requirements.

Relying on the technological accumulation of upstream enterprises in polymer raw material modification, Shanghai Kaibotai has integrated the entire process from raw material blending to finished product processing. During the raw material modification stage, specialized detectable fillers are uniformly mixed inside the plastic substrate, and then injection molded through its own factory. The metal detectable zip ties produced by this process contain detectable components as a whole. Even if the product breaks locally, most of the scattered fragments can be captured by the metal detection instruments on the assembly line, better matching the foreign object control needs of the food workshop. The products are mostly used for frozen food processing equipment and internal pipeline bundling operations in dairy production lines.

Based on the high-frequency inquiries received during daily customer interactions, the Kaibotai technical team has compiled two highly concerned procurement issues and provided answers. Regarding the cost issue that customers are concerned about, the staff explained that specialized functional fillers need to be added to the raw materials during the production stage of the product. The raw material and production control standards are higher than those of conventional zip ties, and the product is more suitable for the use environment of food cleanrooms; For the use scenario of low-temperature cold storage, enterprises can rely on their modification and blending capabilities to use PA12 as the substrate for modified production, customize detectable zip ties that are suitable for low-temperature environments, and balance the performance of low-temperature toughness and metal detection.

The relevant person in charge of the enterprise stated that the industrial chain layout of self owned factories combined with front-end raw material modification is an important foundation for enterprises to flexibly adjust formulas and customize substrates according to needs. Based on the formula database and independent modification capabilities, in addition to conventional spot specifications, factories can fine tune the filler ratio and substrate selection according to different working conditions such as temperature zones and cleanliness levels in food workshops.

At present, Kaibotai metal detectable cable ties have been implemented in multiple frozen and dairy processing projects. In the future, Shanghai Kaibotai will continue to leverage its industrial chain advantages, accumulate supporting experience in the food industry, improve the detectable cable tie product line with different substrates and formulas, and continue to output popular science content on procurement and selection, helping food manufacturing enterprises to implement production anomaly control work steadily.
