WEIGHT OF PET WATER BOTTLE PREFORM HOW TO

Carbon emissions savings: 57,377 metric tons/yearĪs you can see from the numbers, this is a promising business case so far.

Total resin savings: 22,560 metric tons/year.

The current PET preform uses the PCO 1881 neck finish.Īssuming this producer manufactures a yearly volume of 12,000,000,000 units and uses 100% virgin resin, here are the potential resin and costs savings from going lightweight: To illustrate the potential savings from bottle weight reduction, we will explore the real-world example of a brand that converts to a lightweight 26/22 GME 30.37 neck finish and closure for a carbonated soft drink. Method 4: Redesigning the base of the bottle to use less resinįor example, Husky offers the EcoBase preform design that can reduce resin use in the bottle’s base by up to 2.5 percent.Įven when considering the variability in resin prices over the past several months, the economics of lightweighting make a compelling business case, both in the short term and long term. This can be accomplished by altering the preform design with thinner walls and other design changes to the body itself. Method 3: Redesigning the bottle’s body to use less resin For example, depending on your application, you can switch from PCO 1881 to the 26/22 GME 30.37 neck finish, which saves approximately 1.88g of resin per unit between the neck finish and closure. This approach delivers greater resin savings when compared to switching to a lightweight version of your existing neck finish. Method 2: Switching to a new, lightweight neck and closure design In this case, the basic design remains the same, but small modifications reduce the amount of resin required for each unit. Method 1: Switching to a lightweight version of your existing neck and closure systemįor example, if you are using the PCO 1881 neck finish, you can save on resin by converting to the newest lightweight version of this neck. These methods can be implemented individually, or in combination to achieve greater savings.

Each focuses on different components of a PET preform. There are four basic industry approaches to lightweighting.

Some approaches to lightweighting make it easier to adapt to these upcoming legislations.

Staying future-ready: In many markets around the world, legislation will soon call for the use of tethered closures to meet sustainability requirements.

Differentiation: Some approaches to this weight-reduction process involve new neck and closure designs that can be part of a market differentiation strategy.

Offsetting other cost increases: Reducing bottle weight can be strategically applied to offset rising production costs due to increased use of recycled PET, which is more expensive than virgin resin.

Helping with your sustainability goals: Every gram of resin saved also helps you reduce your CO2 emissions.

However, there are many additional benefits: Any opportunity to reduce the amount of resin used in your PET bottles is an opportunity to lower your production costs. The concept of lightweighting as a cost-saving measure is fairly straightforward.

To help you decide if lightweighting is right for your needs, this article provides a quick overview of what is involved and how to make the business case. For example, in addition to helping reduce your production costs, it can play a key role in helping you achieve your sustainability goals.

While this technique has been used as a cost-saving measure for quite some time, approaches to reducing bottle weights are always evolving, and the business case is changing too. Lightweighting your PET preforms and bottles is one way to reduce production costs and hit profitability targets in a relatively short time frame.
