Safe Modes of Polyethylene Terephthalate (PET) Packaging

Thanks to the polymer chemists who formulated polyethylene terephthalate, PET in short, the techniques of packaging have undergone revolutionary changes for the items from the FMCG segment in particular. It was found to be an ideal medium to pack mineral or filtered water, aerated beverages including spirits and liquor, processed syrups, sauces, edible oils, personal care items like shampoo and lotions, detergents, insecticides and industrial oils etc.

Indeed, the FMCG industry found PET to be the most favourable since it was extremely light and unbreakable as compared to the conventional glass, ceramics, tin, and even aluminium. Further the design and size of the packaging too happened to have ample scope for attractive variations and above all,

packaging meant optimum shelf life. However, environmentalists including the NGT (National Green Tribunal) raised doubts over the PET technology despite scientific studies proving that it is no more harmful and that it can be recycled.

Aptly the chemists have renamed this recyclable material as rPET. And the patented eco-friendly rPET product is known as PET Planet and deemed to be the greenest container on the earth. The credit for this innovative formulation, evolved from a process named Reverte is attributed to Wells Plastics, a UK-based company. Among the prime qualities of the Planet containers are that they are made from sustainable sources sans any contaminating additives in plastics

depends on high precision tooled blow and preform moulds for hot runner systems. This process is applicable for caps and closures too. A hot runner system is an assembly of heated components with applications in plastic injection molds to inject molten plastic into the desired cavities of the mold.

The polyethylene terephthalate (PET) has ushered a new era in the packaging of both and non-edible products. However, the overall quality of packaging depends on the PET preform molds inserts, particularly the ones produced on the globally well known Husky brand systems.

Apart from the high grade steel usually imported from Japan or Sweden, the other yardsticks to ascertain the superior quality of a preform mould are –

• Low Preform eccentricity, not more than 0.1/0.2mm
• Low I.V. (Intrinsic Viscosity Loss) Loss
• Low weight variation between cavities, less than +/-0.2 gm
• Excellent Perpendicularity
• Low Preform temperature at exit to avoid scratches on Preform
• Smooth finish
• Flash free
• Accurate Thread Finish for better Closure Fitting
• Uniformity in Wall Thickness with high clarity
• Dust Free
• Almost Zero ‘AA’ level, suitable for beverages

Vishal Beverages Pvt. Ltd. This company has mastered the art of designing and developing moulds with such top precision that while blowing the preform the material is uniformly distributed and thus ensure superior sturdiness and improved transparency.

The preforms are made under rigid quality control conditions here while a fully equipped laboratory ensures that all products meet and even exceed beyond international standards. They are available in a variety of neck and weight categories.

A notable hallmark of

products and services is its expertise in a perfectly balanced hot runner system that ensures uniform melt flow and pressure in all the cavities. Best sliding properties of all moving parts ensures minimal maintenance cost.

Although India’s share is less than five per cent share of the world’s $550 billion packaging industry’s share, the country is making great strides in this segment. For instance, the Indian Institute of Packaging has developed a new technology to pack tender coconut water with higher shelf life and qualities to retain its natural flavour.
