Why is refillable packaging essential?

Single-use packaging creates a huge amount of unnecessary plastic waste. Refillable packaging offers a simple upgrade: instead of throwing away the whole container, consumers keep the outer pack and only replace the refillable inner jar or bottle. This small change can make a big difference. It reduces plastic use, lowers carbon emissions, and helps brands communicate their sustainability goals in a clear and honest way.

How does COSJAR’s Refillable System Help Reduce Waste?

COSJAR’s refillable designs keep things easy. The outer container—made from PMMA, PETG, PP or PET—is manufactured to last and stay looking great. Inside, the PP refill is lightweight and easy to pop in or out.

Because the refill uses much less plastic than a complete set of containers, it can significantly reduce material consumption. For example, one 50ml refillable jar can cut plastic usage by up to 60–75% simply by applying refillable structure. And with less plastic being produced and transported, brands also help lower their overall carbon footprint.

Sizes and Options for Modern Skincare Routines

To match different formulas and product lines, COSJAR offers several refillable options. Refillable bottles come in 20ml, 30ml, and 50ml sizes, perfect for serums, toners, and lotions. Refillable jars are available in 30ml and 50ml and work beautifully for creams, balms and even rinse-off masks. Every container can be customized, whether it’s color, finish, or decoration, so brands never have to compromise on style.

Refillable Packaging Supports EU PPWR Requirements

The EU’s new PPWR regulations are pushing brands to move toward packaging that either uses less plastic, can be reused, or is easier to recycle. COSJAR’s refillable system naturally fits the focus of the regulation. The durable outer container encourages reuse, the PP refill reduces the amount of plastic needed, and the mono-material design supports recyclability. For brands that sell in Europe or plan to, refillable packaging is a smart step toward future compliance.

What refillable packaging does COSJAR offer?

COSJAR offers a number of refillable packaging choices that include airless packs, bottles and jars so that brands can choose between a variety of options.

ARD-50 Airless Jar
The ARD-50 airless Jar has been upgraded so that the airless jar interior can be replaced when the cream or lotion has been depleted. The double-wall pack features a sturdy exterior jar with a glass-like look and a pump dispenser to enable easy product evacuation for the end-user.

The airless system ensures that no exterior contaminants can come into contact with the formulation, making it an ideal choice for natural and preservative-free skincare formulations.

CRD-50 Jar
The CRD-50 cream jar has a 50ml (1.7oz) capacity. It combines an eco-friendly ethos with a luxurious look thanks to its PETG exterior. It benefits from a refillable inner jar to promote reuse and recycling.

Its partner is the CRD-30 cream jar, which is also refillable and available in a 30ml capacity so that brands can choose between different product volume options for their premium cream lines.

CRB-50 Bottle
The CRB-50 bottle is not only refillable, it can be decorated for a tailored experience that reflects your brand's identity.

The 50ml capacity is ideal for a variety of lotion and sprayable formulations.
