The plastic twin of glass


PET is a phenomenal material. It's eminently recyclable. It offers a number of barrier properties not found in other plastics. It can be molded fairly easily. Its clarity is unparalleled. The problem is, when creating containers out of PET, companies tend to approach the material as they would others, using the same proportions, sizing, and thicknesses as they would with other products. The issue is, a standard PET product isn't going to cut it in the luxury space, where consumers are accustomed to a higher level of quality.

SR Packaging (www.srpackaging.com) has a slightly different approach. The option for a standard PET solution is always available from the firm, but for customers seeking to enter or update an existing brand on the luxury market, it offers a series of heavy, thick-walled PET containers that are as analogous to glass as the material can be. When a consumer picks up a glass perfume or cream bottle, it has a heft to it. Glass is often associated with containing a higher quality product than plastic. The tactile sensation is similar, as is the level of clarity. Really, the only difference is the standard weight.

The heavy, thick-walled bottles produced by SRP weigh approximately 54 grams, compared to a comparably sized glass bottle which comes in at about 56 grams. The weight is, therefore similar, and provides the expected heft and feel a luxury shopper would require in a product that costs more than other brands. Yet, each PET container offers the requisite benefits of the material as well as offering one that glass does not: it's very difficult to break.

This is one of the key differentiators of PET, and why it is better suited as a material to be used when travelling, even if it's just out for a night on the town or between home and the gym. Glass may still be the king of household perfume bottles and cream containers, but PET is rapidly gaining ground and is poised to dethrone glass in the "on the go lifestyle" category.

The bottles are produced using painstaking injection stretch blow molding, but are left to boast an average wall thickness of 4 mm, nearly duplicating what one would expect from a PET bottle. The items featured here are done up in green, but can be done in any number of colours. When combined with SR Packaging's wide array of decoration options, the bottles emerge ready to be delivered, glass-like and appropriate for the luxury market. Further, they can be matched to the company's line of heavy, thick-walled jars, which follow the exact same design principal, offering companies a viable receptacle for gels, creams, and other cosmetic, personal care, and cosmeceutical products.

A summary of PET's advantages:

  • PET can be molded to be as heavy as it needs to be.
  • The clarity of PET is indisputable, it is the preferred choice for luxury products.
  • PET offers a vast array of neck size tolerances, so bulk content can be filled easily.
  • As a material, PET is not fragile, it can withstand some punishment.
  • Adding colour to a PET bottle is just as easy as with other forms of plastic.
