Tritan ™ is a copolyester which forms when modifications are made to polyesters. For example, to introduce standard PET with various acids and diols, the material Tritan ™ is created from a chemical process. Copolyesters retain their strength, clarity and other mechanical properties even when exposed to a variety of chemicals. These advantages, combined with the high degree of flexibility, allow manufacturers to use Tritan ™ for a wide variety of product groups.

A few facts about Tritan™

  1. Tritan is a BPA-free plastic – it is not manufactured with bisphenol A (BPA) or the other bispenol compounds, such as bisphenol S (BPS).
  2. Tritan is impact-resistant – products can be used safely without breaking or cracking.
  3. Tritan is strong – it extends the life of water bottles and food containers, reducing waste flow.
  4. Tritan is exceptionally resistant to the dishwasher – the material can be washed almost without any material deterioration.
  5. Tritan is much lighter than glass – making it easier to handle, without the fear of breaking the material.


Zengo strives for the highest quality for its Tritan™ products. We have a partnership with the well known supplier Eastman Chemical, which is the raw material producer of BPA free Tritan™. As a partner we have the advantage that we are the first to be informed of all material and raw material developments. So for Tritan™ innovations you are at the right place at Zengo.

Advantages of Tritan

It is no coincidence that Tritan is one of the fastest growing packaging materials of the moment. The material is characterized by many different advantages in terms of look and feel and applications, but it also offers multiple advantages for the ultimate users. Below is a summary of the 10 top benefits:

BPA-free – All our Tritan™ products are completely BPA-free and can therefore be safely used for all foodstuffs.

Reusable – All the Tritan™ packaging has a long life and can be used more than once. This minimizes material waste and at the same time we combat the nasty phenomenon – “litter”.

Clarity – Tritan™ is indistinguishable from glass and PET in terms of brightness and shiny appearance: Crystal clear. The material also retains these properties even after being used repeatedly.

Dishwasher safe – Just like glass, Tritan™ products are resistant to the high temperatures of a dishwasher. This makes the material perfect for products that are used repeatedly.

Stylish – All Tritan™ products have a glossy appearance, which gives the packaging its stylish appearance.

Good barrier properties – Like other materials, Tritan™ has good and less good barrier properties. The good properties make this material the perfect solution for as an example drinking water bottles.

Microwave Safe – Tritan™ can withstand temperatures of up to 100 ͦC and is microwave safe.

Freezer Safe – The material Tritan™ can be used perfectly for frozen products. The final wall thickness and the filled product partly determine which temperatures are suitable.

Easy to decorate – The material Tritan™ is relatively easy to provide with a screen print, label or sleeve. Similar to glass or PET, you can colour Tritan ™ packaging in different grades with every colour of the rainbow.

Safe – The products are unbreakable and therefore no danger during filling on the filling lines or during festivities.

 Tritan™ is the chosen material for Zengo because of its many advantages. If you want to know more about this specific material, please contact us

Tritan masterbatch


Zengo mainly uses the ISBM production technology (Injection Stretch Blow Moulding). The production is made via a single stage technique. This method is extremely suitable for both small and larger sizes. The process is done in three steps:

Step 1: to the basic form (preform)

The Tritan ™ material is dried and goes from the dryer to the machine via a helical cylinder. During this transport, the granules are heated, resulting in liquid Tritan ™. The liquid mass is then injected into the first mould: the so-called preform mould.

Step 2: to the final shape

The basic shape now receives a neck sprayed with high precision. The blow mould gives the pre-form shape its final shape by providing the elastic part under the neck and blowing it out. Blowing causes the formation of the Tritan™ against the wall of the blow mould, which can produce all kinds of shapes and engravings.

Step 3: towards the final product

Here a removal unit puts the Tritan™ bottle or drinking glass on a conveyor belt on which a check is made that is related to the customer’s customized requirements. After this, the end products are packed in boxes or on pallets.

Safety regulations are strictly enforced in our factory. The plant is BRC certified and has the ISO9001 certificate.
