Compostable milk bottles

At the start of our journey in dairy production, we asked ourselves an important question: “Why are organic and all-natural products packaged in petroleum-based bottles, and why is there no plant-based alternative?” This question sparked the search for a more sustainable solution, and the answer was found in PLA. PLA is a 100% plant-based bioplastic that contains no petroleum or harmful substances.

Compostable Milk Bottles – A Natural Match for Dairy

Milk is one of the most natural products we consume, yet it is still often packaged in petroleum-based plastics. With our PLA milk bottles, we offer a fully plant-based alternative that is safe, sustainable, and perfectly suited for modern dairy production.

Standard and Custom Bottle Designs

Our milk bottles are available with a 38mm neck finish, a format widely used in the dairy industry. We also offer the flexibility to create different designs and sizes to match your brand identity or functional requirements. Whether you prefer a traditional milk bottle look or a more contemporary design, we can develop a solution tailored to your needs.

Preforms and Blown Bottles

We supply both preforms and finished bottles, giving dairy producers the flexibility to choose the production setup that fits best. Preforms can be blown in-house using standard PET blowing equipment, or we can deliver ready-to-fill bottles directly. This flexibility allows dairies of all sizes to integrate PLA packaging without disruption.

Small-Scale Production Lines

For companies looking to expand or start sustainable production, we can also provide small production lines for blowing, filling, and packaging. This turnkey approach enables producers to handle the entire process on-site, from bottle formation to finished product, while maintaining complete control over quality and sustainability.

A Sustainable Future for Dairy

By choosing PLA bottles, you align your dairy products with consumer expectations for healthier, more sustainable choices. Free from toxins and microplastics, and fully compatible with composting, recycling, or safe incineration, our bottles ensure that your milk is packaged as naturally as it is produced.

Why PLA Bottles Make the Difference

Conventional plastic bottles made from fossil resources carry hidden costs. They break down into microplastics that stay in our environment forever — finding their way into water, air, soil, animals and even our own bodies. They can also leach toxic substances into the very products they are meant to protect. For a natural product like milk, this contradiction has never made sense.

Our PLA milk bottles offer a truly different path. Made entirely from renewable, plant-based resources, they contain no petroleum and no harmful chemicals. This means the packaging remains as pure as the product inside. The lower carbon footprint of PLA further reduces the environmental impact of dairy production, helping brands take real action against climate change.

At the end of their life cycle, PLA bottles also provide multiple safe and sustainable options. They are industrially compostable, can be safely incinerated without releasing harmful substances, and are compatible with anaerobic digestion or dedicated PLA recycling streams. Whichever route is taken, the result is the same: no forever plastics, no toxic residues, and no lasting damage to our planet.

With PLA, milk producers can finally offer what consumers increasingly expect — a 100% natural end product, free from toxic packaging and future-proof in every way.

PLA Preform Packaging Specifications for Efficient Global Distribution

To support large-scale production of sustainable packaging, CET Plant-Based Bottles supplies PLA preforms in optimized pallet configurations designed for efficient storage, handling, and international transportation.

This technical information sheet provides a detailed overview of pallet dimensions, box quantities, packing materials, and loading capacities for our PLA preforms. By standardizing packaging and logistics, we help bottle manufacturers, dairy producers, and beverage companies streamline their supply chain while reducing transportation costs.

Our PLA preforms are manufactured from renewable plant-based materials and are suitable for a wide range of sustainable packaging applications, including compostable milk bottles, dairy packaging, water bottles, juice bottles, and other food-contact containers. Each preform is packed in sealed food-grade bags and corrugated boxes to ensure product quality and cleanliness throughout storage and transport.

Whether you are producing compostable milk bottles, plant-based beverage packaging, or other sustainable containers, this specification sheet provides the logistical information needed to plan production, warehousing, and international distribution efficiently.

We make bottles differently

Petroleum-based, single-use plastics such as bottles, caps, straws, and food utensils, clog landfills and contaminate our landscapes and watersheds.

We are dedicated to reducing the usage of environmentally-unsound, single-use plastics. We utilize only non-GMO, plant-based PLA resins for manufacturing our unique biodegradable bottles.

As a result, all of our containers can be disposed of through industrial composting. Or be recycled, incinerated

Some of our benefits

Our caps work

Our 100% caps work. Are leak free, fit your existing bottling line and are 100% industrial compostabl

15+ years of experience

Since 2004 we are making pla bottles and preforms. We have production facilities in the USA and Europe.

Large supply or resin

We work with large PLA resin manufacturers. This will guarantee a steady supply of resin. And makes it possible to produce a large amount of preforms for the water, juice and dairy industry.
