For plastic bottles, the greatest degree of material savings, in addition to the bottle itself, the design of bottlenecks and caps can not be ignored components, but it is particularly important not to forget to change the design of the bottleneck while ensuring or To improve the adaptability of the bottle type to the existing production line, it must take into consideration the maximum compatibility with the existing preforming equipment, blow molding equipment and canned equipment.
Short bottleneck technology
In order to reduce the material costs of PET bottles as much as possible, many companies have launched their own short bottleneck technologies. A lot of technology makes the processor often confused: what kind of choice should I use? But one thing is obvious: saving material when choosing a bottle type is not the only factor that needs to be considered.
First of all, it is very important that the short bottleneck surface is compatible with the existing bottleneck structure. This will directly affect the existing preforming tools, blow molds and canning and capping lines.
The sealing performance of the cap is also an important aspect that cannot be ignored. In tropical countries, the condition of the road surface may be poor. For soft drinks or mineral water filled with a large amount of CO2, the bottle cap is required to have excellent sealing performance. PCO Corvaglia is the only bottle design that completes two or more threads on a short bottleneck. Its sealing performance is obviously not a bottleneck structure, if only one thread can be compared. In addition, the PCO Corvaglia surface can be adapted to different sizes of bottle types as well as different types of caps.
For aerated beverages, the release of internal pressure when opening the cap should also be a controlled process and it must be avoided that the caps fly out to injure consumers. Here, PCO Corvaglia's 744° single head thread once again demonstrated its superiority. Other short-bottleneck structures are generally less than two-turn threads, and the use of two or three threads has a greater risk of ejection.
Save material
Compared to the standard PCO 28, PCO Corvaglia's short bottleneck can save 1.5g of PET stock per bottleneck. In addition, the cap can save 0.7-1.2g of raw materials. Corvaglia is able to provide three bottle cap designs that use PCO Corvaglia bottlenecks. The lightest one is only 1.8g for ungassed water or beverages; 2g and 2.3g caps are used for aerated beverages, of which 2.3g is used for aerated beverages. Based on current raw material prices, the use of this technology saves approximately 2.9-3.5 euros per 1,000 bottles of raw materials on bottles and caps.
Capping equipment can be fully produced
Due to the short-range design of the anti-theft ring and the thread, only PCO Corvaglia can use the bottleneck anti-theft ring design of PCO 28 or PCO 19. Other short-bottleneck designs are often subject to certain restrictions, for example, the use of a folded anti-theft ring, etc., in order to not affect the capping performance.
