Japan's Aoki Corporation is a professional manufacturer of injection stretch blow molding machines and launched Ugly Duckling, an ultra-thin, ultra-light plastic bag with cover.
In order to develop Ugly Duckling, Aoki uses the latest molding technology: a one-step, three-station direct thermoforming method. The specifications of this plastic bag are 16 g, weight, 1.5 liters, weight 14 g, capacity 1 liter, weight 11 g, capacity 750 ml. Compared to ordinary PET bottles, the weight of this new plastic bag is reduced by 50%. This ultra-light, lidded plastic bag is easily deformed and cannot stand upright when full. In addition, it also brought many problems related to molding, filling and promotion, so Aoki named it Ugly Duckling.
When you touch this plastic bag, you will be surprised at how soft it is. It is as thin as a plastic film, and it consumes half the amount of resin in a conventional container. Although thin, it has the same or even greater drop strength than ordinary PET bottles. After use, consumers can easily knead it into a ball by hand, which can greatly reduce the volume of local waste. By reducing raw material consumption and waste disposal, this new type of plastic bag has great advantages in reducing the environmental burden.
Ugly Duckling plastic bags can also bring many other added value. Its flat shape makes it very portable. Its opening is not in the center, plus it's very easy to squeeze, so it can easily and quickly pour out more viscous liquid. Because of the squeezable and capped nature of this plastic bag, if it is loaded with a product that is easily oxidized, when the product is used, the air in the bag can be easily extruded, thus reducing the product's Air exposure opportunities delay the oxidation process.
