摘要:

基于白酒塑料包装制品在存储过程中,由于燃油装载车辆排放尾气中的NOx而导致出现气熏黄变现象,通过建造人工环境,研究了不同种类的白酒塑料包装制品在高浓度NOx环境下的黄变、抗腐蚀性和热稳定性等的变化情况,以期确保高端白酒包装选材在正常使用、储存过程中不失效,避免防伪方面出现漏洞。结果表明,在超高浓度NOx(2 480 mg/L)气氛下,烫金的醋纤维素(CA)制件与丙烯腈?丁二烯?苯乙烯共聚物(ABS)真空镀膜件会失去金属颜色,导致包装上关键防伪标识无法辨别,影响包装防伪效果;CA制件与聚酰胺(PA)织布袋经NOx试验后,缩短了制件的设计使用寿命;金属化包装制件、烫金膜等制件的表面涂层适当加厚,稳定剂适量增加,可一定程度上延长制件的稳定期;被NOx侵蚀后,CA件与PA织布袋会因NOx溶解或降解、烫金件与蓝色制件褪色、聚丙烯(PP)件脆化、聚甲基丙烯酸甲酯(PMMA)件龟裂。

Abstract:

Based on the yellowing phenomenon caused by the NOx gas emission of gasoline?loading cars in the storage process of plastic packaging products for liquor, the different types of liquor packaging products in high concentration of NOx environment yellow change, corrosion resistance and thermal stability were investigated through the construction of artificial environment. This can ensure the normal use of high?class liquor packaging materials without any failures during storage and also avoid loopholes in anti?counterfeiting. The results indicated that the vacuum coated parts of gilded cellulose acetate (CA) and acrylonitrile butadiene styrene copolymer lost their metal color under the atmosphere of ultra?high concentration of NOx (2 480 mg/L). This resulted in a failure to distinguish the key anti?counterfeiting marks on the package and affected the anti?counterfeiting effect of the package. The design service life of CA parts and polyamide (PA) woven bags was shortened after the NOx test. The surface coating of metallized packaging products, bronzing film and other products was thickened appropriately, and the stabilizer was increased appropriately. This prolonged the stabilization period of the products to a certain extent. After eroded by NOx, the CA and PA woven bags were dissolved or degraded by NOx, the blue parts and the bronzing parts faded, the polypropylene parts became brittle, and the polymethylmethacrylate parts cracked.
