Nano-composite packaging materials will be rapidly industrialized with the rapid development of nanotechnology. Because of its obvious improvement, such as abrasion resistance, hardness, strength, barrier property and plasticity, it can be used for special packaging in addition to food packaging. Such as anti-static, anti-electromagnetic, anti-explosive and invisible, dangerous goods packaging, etc., it is expected to promote the transformation of traditional cosmetic plastic soft tube materials.
Environmentally friendly (environmentally friendly) cosmetic plastic soft tube material (or green cosmetic plastic soft tube material), with the implementation of the environmental management standard IS14000 series has become a global hotspot, among which the easy to recycle and use of cosmetic plastic soft tube materials such as PET PEN, biodegradable plastics in environmentally-friendly plastics (EDP) have become hot spots in the hot spot. Others such as zero-pollution foam, thin-walled bottles and bag-shaped packaging containers have also attracted much attention.
In the packaging of juice and tea beverages, hot-filled plastic bottles have lower cost, transparent material, light weight, and are not easily damaged, and have good environmental adaptability, etc. compared with traditional aseptic paper packaging, three-piece metal cans and glass bottles. The advantages have been obtained in an increasingly wide range of applications, accounting for more than half of the total hot pack market. In addition to PET, hot-filled plastic bottles have received much attention in recent years. The BOPP bottle has the following advantages: the heat resistance is improved by the PP stretching process, the canning temperature can be increased to 100 degrees Celsius, the bottle mouth does not require special equipment treatment, and the oxygen barrier performance is greatly improved; the BOPP bottle does not absorb moisture, The storage period is long and easy to recycle; the product cost is 20% cheaper than PET bottles.
