The safety of Custom Spout Pouches bags is first reflected in the precision of their sealing structure. The sealing strength achieved by ultrasonic welding technology can reach 45 Newtons /15 millimeters, and the leakage probability is reduced by 90% compared to traditional packaging. According to the 2024 assessment report of the European Food Safety Authority, the secondary sealing performance of the custom mouth bag equipped with a screw cap keeps the oxygen permeability below 0.5cc/m²/ day, extending the shelf life of products such as tomato sauce from 6 months to 12 months. For instance, after Nestle’s condiment brands adopted the leak-proof bag design, the complaint rate of damage during transportation dropped from 3% to 0.2%, reducing product loss by 1.2 million US dollars annually. This packaging has passed the sealing integrity test, can withstand temperature fluctuations from -40℃ to 120℃, has a compressive strength exceeding 80kPa, and ensures an integrity rate of 99.8% under a supply chain vibration frequency of 15Hz.
In terms of material safety, the custom mouthpiece uses an FFDA certified food-grade polyethylene inner layer with a heavy metal content of less than 0.1ppm, meeting the requirements of the EU regulation 1935/2004. Swiss SGS test data shows that its multi-layer composite structure reduces the photo-oxidation rate by 75%, and the vitamin C retention rate is 40% higher than that of transparent packaging. For instance, Danone baby food uses custom mouth bags made of aluminum foil lamination, with a UV blocking rate of 99.8%. Under an illuminance of 5000 lux, the pigment degradation rate drops by 60%. The 2023 Global food packaging safety audit shows that the incidence of microbial contamination incidents in such packaging is only 0.03 times per million cases, which is far lower than the industry average of 0.15 times per million cases.
The tamper-proof design enhances the security level. The opening torque of the custom mouth pocket’s breakpoint seal cover needs to reach 0.7-1.2 Newton-meters, reducing the probability of children accidentally opening it from 23% to 5%. According to data from the U.S. Consumer Product Safety Commission, poisoning incidents of detergent products packaged in this way have decreased by 65%, with the pressing and rotating operation force of the safety cap set at 15 pounds, exceeding the hand strength limit of a 3-year-old child. The case of Procter & Gamble’s laundry pod packaging shows that the number of complaints about accidental ingestion of custom mouth bags has dropped from an average of 150 per year to 12, and the amount of insurance claims has decreased by 80%. This design has passed the ASTM D3475 standard test. The success rate of adult opening is 98%, while that of traditional packaging is only 85%.
The intelligent protection features further enhance safety. Some high-end custom mouthpieces are integrated with temperature-sensing labels, which will issue a color change warning within 2 hours in an environment above 8℃, with an accuracy rate of 99.5%. The smart mouth bag solution showcased at the 2024 Pharmaceutical Packaging Innovation Summit has reduced the product traceability time from 48 hours to 2 hours through a QR code traceability system, lowering the recall cost by 70%. For instance, Mars Pet Food has adopted custom mouthpieces equipped with blockchain technology, enhancing the traceability accuracy of contamination incidents to 100% and increasing the efficiency of handling customer complaints by 300%. The anti-counterfeiting label verification pass rate of this packaging is 100%, reducing the risk of counterfeit products entering the market by 95%.
