Top Quality Package Deals in PET Packaging

Presently, the modes of packaging thousands of edible and non-edible items are based on PET (polyethylene terephthalate) technology in which plastic injection molds give the shape and size of the desired container, be it the bottle or a jar. This is enabled by the hot runner systems that happen to be complex of heated components regulating the injection of the material in the cavities.

The concept of hot runner systems was initially developed during early 60s but gained popularity three decades later. One of the reasons for such delayed implication was the notion about PET containers not being environment friendly until scientists proved that PET is a recyclable material. Above all, the users realised that the hot runner systems are very cost effective and economical in the long run. Read more

Caps and Closures in PET Packaging

The success of a PET packaging unit depends on the quality of the moulding facilities provided by the manufacturer of the system. The ultimate utility of the bottle or jar is proven by the superior properties in the caps and closures. These should possess high standards in terms of being leakage and pilfer proof. This is ensured when the cap closure mould manufacturer is of repute.

Such a company should have top class infrastructure for design and development of wide range of perfect PET moulds for the caps and closures to suit various patterns of the moulded packing containers. The moulds need to possess optimum properties for high-speed, high cavitations, high-volume applications. The hot runners need to be balanced for consistency in cavity-to-cavity filling. This is vital since a hot runner undergoes melt channel sizing analysis where balance, shear rate and pressure drop are optimized.

How hot runner system reduces cost?

A hot runner system is an integration of heated components used primarily in plastic injection molds. It helps inject molten plastic into the hollow cavities of the mold. Where as, a cold runner system is simply a channel in between the two halves of the mold, designed to carry plastic from the injection molding machine to the cavities.

Every time the mold opens up to eject the newly formed plastic parts, the runner material is ejected too. This result in the wastage of the plastic deployed. On the contrary, a hot runner system includes a heated manifold. The primary purpose of the heated manifold is to allocate the plastic entering in the mold to the various nozzles and measure the injection points in the cavities.   Read more
