PTI effectively reduces the weight of plastic bottles

Many packaging manufacturers are committed to reducing the weight of the package, and to spend more energy on the appearance of the package, from the consumer's point of view, to produce a plastic bottle that is easy to use and generous appearance. Today, a new injection stretch blow molding technology is used in the plastic bottle production process, which can produce a very convenient handle plastic bottle.

Plastic Technologies believes that its new technological breakthrough for plastic bottles will provide users with a great opportunity to reduce the weight of plastic bottles by 25%, allowing the company to devote more attention to the aesthetics of packaging. On the other hand, especially in the pursuit of high-definition in general companies.

On November 1st, at the packaging exhibition, PTI's director of customer development and marketing was interviewed and said: "This new PET bottle can bring better market impact to its trademark owners. Our goal is to develop User-friendly packaging. This type of packaging bottle is better than the bottle made of mixed material on the market. It can make it easy for consumers to pour the liquid from multiple plastic bottles at the same time."

He added: “At this exhibition, we only introduced some samples of plastic bottles. Trademark holders are always looking for more convenient hand-held bottles. They need to survey their users for useful information. ."

PTI said that they had tried to make DeepGrip bottles in the past. Using injection stretch blow molding, it did bring some benefits compared to the extrusion blow molding process (representative technology with hand-held bottles).

According to PTI, the benefits of injecting stretch blow molding include: May reduce bottle weight by 20%-25%, export volume reaches 1200 per hour, have a smaller device footprint and better drop and resistance Creep performance.

“Those brand owners are usually like controlling the weight of the package, and spending more on improving the appearance of the bottle to provide a way to identify their products. Deep Grip technology is an ideal choice.” PTI Europe The general manager added.

PTI Europe will first promote Deep Grip plastic bottles to the market. They are cooperating with the French Sidel Group in Le Havre, one of Switzerland's TetraLaval International SA, which operates the three major industries.

Deep Grip plastic bottles put the initial market goals for clean bottles, daily cleaning plastic bottles, plastic bottles for milk, cooking oil and motor oil, baby bottles, and plastic bottles of non-carbonated beverages including juice, tea, and water.

Puvak said: "In this technology we have been working closely with Procter and Gamble. They both tend to be consumers and want to develop a plastic bottle that is more convenient for consumers to hold and dump."

Injection stretch blow molding process adds a handle to the plastic bottle. This handle can hold more than 25mm or 1 inch on each side of the plastic bottle, or it can be less than 0.3mm or 0.1 inch. Such a large hand grip range will Will make it replace the traditional bottle with handle.

The bottle and its embedded handle are produced using the same raw material on the Sidel equipment using a two-step process. This kind of bottle first passes through the traditional stretch blow molding process, and then a further injection process on the same device becomes the handle. In addition, injection stretch blow molding eliminates the manufacturing process by allowing plastic bottles to be blown and transferred for filling operations.

According to PTI, precisely, this technology gives brand owners great flexibility in grasping the handles, shapes, and diameters of plastic bottles. It can make plastic bottles as large as 6 liters or 1.5 gallons, with a diameter of 220 millimeters or 8.6. inch.
