370ml flint bamboo shoot bottle food jar
In the food packaging glass container industry, the 370mL bamboo shoot bottle is a specialized container designed specifically for packaging edible bamboo shoots. It is suitable for various ready-to-eat and pickled bamboo shoot products, as well as other foods. With its precise capacity design and adaptability, it has become a common packaging choice in the bamboo shoot processing industry, meeting the core requirements of safe and practical food packaging glass containers.
The core advantages of this bottle size align with the actual needs of bamboo shoot packaging: no risk of bottle mouth shattering, effectively avoiding leakage and contamination problems caused by bottle mouth breakage during packaging and transportation; the bottle body meets roundness standards, facilitating automated filling and sealing operations while improving stability during storage and stacking; the bottle mouth size is highly controllable, meeting the requirements of the GB 4806.5-2021 national food safety standard, precisely matching the sealing cap to ensure sealing and prevent bamboo shoot spoilage.
During production, this bottle exhibits three common online defects: misaligned printing at the top, uneven bottom, and bottom edge cracks. These defects are mostly caused by deviations in molding process parameters. Misaligned printing at the top and uneven bottom are appearance and stability defects, while bottom edge cracks may affect the container's pressure-bearing capacity. To ensure product quality, our company has established a comprehensive quality control system: integrated machines adjust and remove products with misaligned printing, manual quality inspection focuses on uneven bottoms, and products with cracked bottom edges are rejected by the inspection machine, ensuring that unqualified products do not proceed to the next process.
Special attention must be paid to the fact that bamboo shoots require high-temperature heating after canning. The bottle's thermal stability temperature difference must be controlled within 45 degrees Celsius. Thermal stability is a core performance indicator; if thermal stability is not up to standard, damage and cracking are likely to occur during high-temperature heating. Therefore, all bottles that fail the thermal stability test are strictly prohibited from bottling, ensuring food safety and product qualification rates from the source, meeting the key requirements for heat shock resistance of food-grade glass bottles.
