What are the key process steps and quality control points in the production process of condiment BIB packaging?
The production process of condiment BIB (Bag-In-Box) packaging is a complex process that combines advanced technology and strict quality control, aiming to provide customers with safe, efficient and customized packaging solutions. Our company, as a leader in this field, is not only equipped with an internationally leading bag-in-box production line, but also has a professional team with more than 15 years of industry experience, committed to continuous exploration and innovation to meet the diverse needs of local and global customers for condiment BIB packaging.
Key process steps
Material selection: According to the different characteristics of condiments (such as acidity and alkalinity, oil content, sensitivity to oxygen and light, etc.), we select high-barrier or ultra-high-barrier film materials, such as EVOH (ethylene-vinyl alcohol copolymer), PET (polyethylene terephthalate) and aluminum foil composite structure to ensure the effective barrier performance of the packaging.
Pretreatment: The material must undergo strict cleaning and anti-static treatment before entering the production line to ensure that there is no dust and oil on the surface of the material, and to improve the bonding strength of subsequent printing and heat sealing.
2. Printing and plate making
High-precision printing: Multi-color gravure printing technology is used, combined with advanced color management system to ensure high clarity and color accuracy of patterns and texts, and enhance product brand image.
Plate making: Design and produce printing plates according to customer needs to ensure that patterns and texts are consistent with product characteristics and meet food safety standards.
3. Bag making and molding
Automatic bag making: Through high-precision automatic bag making machines, the pre-treated film materials are cut and heat-sealed into bags according to preset sizes to ensure good sealing and no leakage of the bag body.
Molding and filling preparation: After the bag body is formed, it enters the filling preparation area through an automatic conveying system. At this stage, it is necessary to ensure that the bag mouth is flat to facilitate subsequent filling and sealing.
4. Accurate filling and exhaust
Accurate filling: Using a precise metering filling system, the filling speed is adjusted according to the different viscosities and densities of the condiments to ensure that the net content of each bag of product is accurate.
Exhaust treatment: Exhaust operation is performed simultaneously during the filling process to reduce residual air in the bag and extend the shelf life of the product.
5. Heat sealing and secondary inspection
Heat sealing: Use high-frequency heat sealing technology to ensure that the bag mouth is firmly sealed and avoid heat damage to the product during the heat sealing process.
Secondary inspection: Through machine vision and manual double inspection, the heat sealing quality, packaging integrity and appearance are inspected one by one to ensure that each product meets the quality standards.
Quality control points
1. Raw material quality control
Each batch of raw materials must be audited by the supplier and inspected for incoming goods, including but not limited to physical property testing, chemical composition analysis, barrier performance testing, etc., to ensure that the materials meet food safety and packaging performance requirements.
2. Production process monitoring
Implement full-process online monitoring, use sensors and automated control systems to monitor the production environment (such as temperature, humidity), equipment operating status and product quality parameters in real time, and promptly detect and correct deviations.
3. Finished product inspection and testing
Finished products must undergo strict physical property testing (such as tensile strength, tear strength), barrier performance testing (such as oxygen permeability, water vapor permeability), sealing testing and microbial testing to ensure that the products meet food safety standards and customer-specific requirements.
4. Customer customized services
In view of the specific condiment characteristics and market needs of customers, we provide a full chain of customized services from material selection, design to production to ensure that product packaging not only meets functional needs, but also enhances brand image and market competitiveness.
5. Continuous improvement and innovation
We continue to invest in research and development to explore the application of new materials and new processes, such as the research and development of biodegradable materials to reduce environmental impact; at the same time, we use big data analysis to optimize production processes and improve efficiency and quality stability.
The production process of condiment BIB packaging is a system engineering that integrates high technology, high precision and high quality control. With advanced production lines, professional technical teams, strict quality control systems and continuous innovation capabilities, our company can provide customers with a full range of customized solutions from design to production, from raw materials to finished products, ensuring that each BIB packaging can accurately meet customer needs and help customers stand out in the fierce market competition.
