Black Plastic Jar, White Lid, 500 ml

The black 500 ml container with a white lid is designed for thicker products that are scooped out with a spatula or by hand: body butters, scrubs, bath salts, clay and hair masks, or family-size packs of cream. The Plastic container, 100 mm, black, 500 ml set consists of a PET container, a white lid with a thread and a white membrane, which is inserted into the lid and improves the seal between the lid and the neck.

The opaque black wall shields the contents from light, which helps with products containing oils, butters and light-sensitive active ingredients. It also hides any uneven colouring of the product. The plastic is lightweight and does not break when dropped, so the container is suitable for the bathroom, the workshop and for transport.

All three parts of the set are approved for direct food contact, so the container can also be used for homemade spice blends, dried herbs, salt, sugar or other loose raw materials. Suitability for contact with cosmetics is declared for the whole set.

Nominal and total volume

The nominal volume is the amount the container is designed for under normal filling. The physical volume up to the rim is larger, because a reserve must remain above the level of the product for the lid with the membrane and for the expansion of the contents when the temperature changes. The container should therefore be filled to the nominal volume, not to the rim. For scrubs and butters, which settle further after filling, also leave room for levelling the surface.

Lid and sealing

The lid is screwed onto the thread of the container and the membrane inside the lid sits against the neck. With thick products such as butters, balms and scrubs, the set holds the contents even when turned upside down or carried in a bag. For runnier products, for example gel scrubs or thin hair masks, we recommend checking the seal on a test piece: fill the container, close it, turn it upside down and leave it standing for several hours.

Closures with the same neck type and ready-made packaging and closure combinations are available in the Handymade range. If you use your own combination, we recommend checking the seal and the behaviour of the packaging with your specific formulation.

What to know before filling

• Preparation – before first use, wash the container, lid and membrane, disinfect them with isopropyl alcohol or ethanol and let them dry completely. Residual water dilutes the product and increases the risk of microbial growth.
• Filling temperature – the container is not designed for hot filling. Before pouring, let melted butters, balms and emulsions cool at least to the point where the mixture starts to set. Do not pour the hot mixture straight from the pot into the container.
• Essential oils and solvents – for products with a higher proportion of essential oils, fragrance compositions or alcohol, first fill one test piece and after several weeks check the surface of the container and the fragrance of the contents.
• Reuse – after washing and disinfection, the container and the lid can be used again. When refilling, check the membrane and replace it if it is deformed.
• Recycling – the container, lid and membrane are made of different plastics. Separate them before disposal so that they can be sorted by material.
