From raw materials to finished products: How does a 35-year-old factory ensure the stable and reliable packaging of every roll?

In the fruit and vegetable and food packaging industry, "stability" is the core requirement for European and American businesses when choosing partners. Data shows that fluctuations in packaging quality can lead to an increase of more than 30% in fruit and vegetable losses during distribution, and for every 1% increase in the non-compliance rate of food packaging, the procurement costs for businesses will increase by 2.8%. As a source factory with 35 years of experience in the packaging industry, we focus on the production and customization of fruit and vegetable packaging bags and food packaging bags. Through meticulous control of the entire process, we ensure consistent quality for every roll of packaging, making us a long-term trusted partner for European and American businesses.

 

I. Raw Material Control: Ensuring Quality from the Source

Raw materials are the foundation of packaging quality. We consistently select food-grade raw materials that meet international food contact requirements and strictly adhere to the principles of "batch testing and full traceability" to mitigate potential quality risks from the source.

①The outer film is preferably made of PE or CPP: PE material has good flexibility and moisture resistance, accounting for 48%-55% of the global fresh food packaging raw materials used, and is suitable for the basic preservation needs of various fruits and vegetables; CPP material has high transparency and stable temperature resistance, and the light transmittance can reach more than 90%, which meets the display needs of supermarkets in Europe and the United States. Each batch of raw materials is tested for thickness deviation and tensile strength, and unqualified raw materials are resolutely not put into storage.

②The inner membrane is made of OPP, PET, and PA materials: OPP material has good stiffness and strong printability, and can meet customized printing needs; PET material has excellent barrier properties and tensile strength more than 3 times that of PE, which can effectively extend the shelf life of food and fruits and vegetables; PA material is puncture resistant and low temperature resistant, and is suitable for long-distance cold chain transportation. All inner membrane materials are tested for solvent residue and oxygen barrier properties to ensure compliance with international food contact standards.

II. Process Control: Refined Production, Eliminating Quality Fluctuations

With 35 years of experience, we have established a standardized production control system, integrating quality requirements into every production stage, controlling losses within the factory, and ensuring the stability of mass production.

①Precise temperature control and process parameters: The lamination and heat sealing processes adopt an online real-time monitoring system, and the error of heat sealing temperature, pressure and speed is controlled within ±2%, ensuring that the sealing strength compliance rate is stable at over 99.5%, which significantly reduces the bag breakage rate in long-distance sea and cold chain transportation to Europe and the United States.

②A comprehensive inspection mechanism is in place: from raw material feeding, film lamination, printing, cutting to bag making, sampling inspections are conducted every hour, focusing on indicators such as dimensional accuracy, printing clarity, and sealing performance, to prevent batches of unqualified products from being released.

③Optimized to meet European and American needs: Combining the distribution habits of fruits, vegetables and food in Europe and America, the packaging has been optimized for air permeability and moisture barrier performance. For cold chain transportation scenarios, the low-temperature resistance of PE and CPP materials has been enhanced to ensure that the packaging does not crack or leak in environments ranging from -18℃ to 0℃.

III. Finished Product Control: Strict Inspection to Ensure Quality Upon Delivery

Finished product inspection is the last line of defense in quality control. We adhere to the principle of "every roll must be inspected, every batch must be checked" to ensure that every roll delivered to European and American merchants meets expectations.

①Multi-dimensional finished product inspection: Before leaving the factory, each roll of packaging undergoes multiple tests, including sealing, puncture resistance, low temperature resistance, and light transmittance. All unqualified products are reworked to ensure that the finished product qualification rate reaches more than 99.8%, which is far higher than the industry average qualification rate of 95%.

②Batch traceability management: Establish a dedicated traceability file for each batch of products, recording in detail the raw material batch, production parameters, and inspection results. This allows for rapid traceability of the entire production process of each roll of packaging, meeting the demand for supply chain transparency from European and American businesses.

③Customized quality adaptation: We flexibly adjust the material combination (PE/CPP outer film + OPP/PET/PA inner film) to meet the packaging needs of different types of fruits, vegetables and food in Europe and America. From thickness and size to printing and perforation, we meet the customer's needs throughout the process to ensure that the customized products are highly consistent with the customer's expectations.

IV. 35 Years of Dedication: Winning Trust Through Stability, Fostering Cooperation Through Professionalism

For 35 years, we have been deeply committed to the industry, consistently prioritizing "stable quality" as our core competitiveness. Leveraging food-grade raw materials, meticulous manufacturing processes, and rigorous finished product inspection, we have become a long-term partner for numerous fruit and vegetable/food retailers in Europe and America. We support full-category customization services, optimizing material combinations and product structures according to customer needs. With mature technology and stable delivery, we help European and American retailers reduce distribution losses and enhance product competitiveness.

For European and American businesses, consistent packaging quality is key to reducing costs and maintaining a strong reputation. With 35 years of industry experience, we meticulously control every step from raw materials to finished products, ensuring the highest quality and building a solid foundation for long-term partnerships with our global clients through every roll of reliable packaging.
