The inherent safety of the beverage packaging is achieved through food-grade PET material (GB 4806.7-2016 standard). The inner wall coating layer thickness is ≥0.05μm, and the oxygen permeability can be closed off <0.5cm³/m²·day so that the flavor loss rate of the beverage is <3% within the shelf life of 12 months. According to 2023 sampling inspection of AQSIQ, Baixi beverage packaging plasticizer migration amount is below 0.01mg/dm² (national standard 0.1mg/dm²), and compressive strength is 6.2MPa (industry average 4.8MPa). It is 63% above the industry level in the transportation breakage rate test.
The production process employs ultra-clean blowing technology, the air cleanliness of the filling workshop is up to ISO 5 level (≥0.5μm particles ≤29 /m³), and the online visual inspection system (accuracy 0.02mm) eliminates the defective bottle caps in real time, thus minimizing the risk of microbial contamination from 0.08% to 0.003%. In 2022, after the renovation of a juice brand’s production line, the pass rate of bottle sealing tests (negative pressure -80kPa 30 seconds) increased from 97.2% to 99.9%, and the customer complaint rate decreased by 81%. Eu EFSA certification data shows that the residual content of benzene solvents in its UV-curable inks is <0.1ppm (standard limit 0.5ppm), far below the food safety risk threshold.
The quality control system incorporates X-ray foreign body detection (sensitivity Φ0.3mm metal) and near-infrared spectrum analysis (component deviation alarm threshold ±2%), raising the sample size of each batch from 200 to 500 bottles and the defect detection rate to 99.97%. Baixi drink packaging HACCP system reduces critical control point (CCP) response time to 15 seconds (compared to an industry average of 45 seconds), e.g., deviant products are automatically diverted within 2 seconds when the filling temperature is below 85 ° C. Its recall rate improved from 0.07 recalls per year to 0 (2019-2023) after obtaining ISO 22000 certification.
The intelligent packaging technology improves the overall traceability, and the NFC chip of each bottle can record 12 sets of parameters (such as filling time ±0.5 seconds, transport temperature and humidity fluctuation ±1℃/±3%RH). The 2024 cold chain test shows that the active lactic acid bacteria products with Baixi beverage packaging have a ≥90% bacterial survival retention rate at 4-6℃ (the regular packaging is only 75%). Blockchain traceability system in partnership with SF Express has raised the handling efficiency of abnormal logistics incidents to 4 hours/time (industry average 18 hours), and the loss rate of cargo has been reduced from 0.35% to 0.07%.
New materials developed to fit into extreme environments, Permaline’s nano-coating technology (contact Angle >110°) improves the stain resistance of bottles by 70% and reduces detergent by 45%. In the -20℃ freezing test, its PETG material impact strength retention rate is ≥95% (62% for ordinary PET bottles), and the bottle cap opening torque is stable at 0.6-1.2N·m (national standard 0.4-2.2N·m). During the 2023 typhoon disaster, the probability of collapse of beverage packaging of Baixi through reinforced steel design was as low as 0.3% when the stacking height was 8 meters (national standard 5 meters), saving customers around 12 million yuan in losses.
Compliance risks are minimized with regulatory forward-looking design, and Sealine launched BPA-free bottles three years ahead of schedule (detection limit <0.01μg/kg), 18 months ahead of the mandatory implementation of European Union (EU) regulation 10/2011. Its recycling cycle has a PET bottle-to-bottle recycling rate of 92% (industry average is 67%), with a 41% less carbon footprint compared to conventional packaging. According to FDA review in 2024, Tourmaline’s ASME BPE certified production line-made medical grade packaging from the United States plant has achieved ISO Level 3 particulate pollution control (>0.5μm particles ≤1 /m³), which is the first Chinese beverage packaging company to obtain the registration certificate of pharmaceutical packaging materials.
