About us Environmental

Pack Tech Moulding Limited is focused on minimising the impact of packaging on the environment and passionate about protecting New Zealand’s clean green reputation.


We understand that the environmental and economic choices we make today has an impact now and in the future. In recognising the need for sustainability, our focus is on ensuring we provide the best sustainable options commercially available, and this is reflected in our approach of ensuring all packaging manufactured by us is 100% recyclable and re-useable.

We are committed to finding innovative and responsive ways to deliver improved outcomes for our customers, ensuring that together we are pro-actively responding to the global sustainability issues through the promotion of a circular plastic life cycle. This is where we strive to keep materials in circularity for re-manufacturing or down cycling. Through design we place high importance on working in mono materials so that they can be easily recycled and are innovative, thinking outside of the square, to ensure a good balance between product performance and the amount of plastic used.

Our zero waste to land fill policy ensures that all waste generated on site is either processed back into products we manufacture or sent off site to a local compounder for conversion. Currently over …..% of the products we make are made from 100% post-consumer waste. The inclusion of recycled material is not suitable for all products, but within the regulatory boundaries, PTML endeavours to promote the use of recycled materials in suitable applications. Our response to the growing trend in a circular economy prompts us to always be looking for innovative ways to use recycled content in products.

At Pack Tech our packaging is made from High Density Polyethylene (HDPE) and Polypropylene (PP). Polypropylene (PP) is used extensively in food packaging because it does not contain any additives dangerous to consumers. Not only does it extend the shelf life of many products, it also gives the food manufactures a variety of filling options which other polymers cannot. It is light weight and fully recyclable, even with it’s in mould label. The other reason why PP is preferred is that it has the lowest density to yield ratio of all polymers, creating greater efficiencies overall.

At present there is no alternatives available to us that provide a better environmental and sustainable story than PP and HDPE.  Many alternatives are not suitable for injection moulding of thin containers and lids due to the rheology of the plastic or the lack of their downstream properties to protect the food and the consumer.  This is why sustainability is at the heart of our business. 

We believe the key to sustainability is tied to finding innovative ways to minimising waste, improve efficiencies and maximising  the resources available.  We undertake to educate ourselves and others in our sustainability vision and to passionately seek ways to recycle, re-use and actively participate in finding viable solutions through design that help in developing our circular economy.






Many non-food-grade containers can be made with recycled plastic, this is a growing market which Pack Tech encourages and can provide for.
