FAQs

Under certain conditions, some substances react to the plastic used in the manufacture of plastic containers. These substances include solvents, cleaning products, cosmetics, tanning products, chemical substances and agricultural products such as pesticides and herbicides. When the contents of a plastic container or bottle react with the plastic, this can cause the container to cave or give a “sucked in” appearance – where the container looks like it has been crushed or squeezed in the middle. Fluorination is a process that is applied to the plastic to preserve the integrity of plastic containers. During the fluorination process, a coating is applied to the inside of the container to offer an extra layer of protection against permeable liquids.

Fluorination can also help protect against discolouration of the plastic. Fluorination doesn’t wear off and is a permanent seal to the plastic.

UN Approved or UN Certified packaging containers are containers that have been officially approved and certified for the transportation and sending of goods on the UN Dangerous Goods List. UN approval means that the products have passed stringent testing for the transport of hazardous goods and substances. UN Approval certificates are available from your account manager on request. In order for the UN Certified, or UN approved status to remain valid, the packaging must be used strictly in accordance with the approval documents.

Lacquered refers to the internal coating available on some of our metal containers. Where a product is described as plain interior, then no coating has been applied.

Where a product is described as having a lacquered interior, a protective coating has been applied to protect either the contents of the container or the integrity of the metal where there is a risk of the metal reacting with the contents.

A good example of this is where an internal coating protects the metal container from rusting and oxidisation when holding water-based products.

Another example is protecting food from metal contamination or discolouration or acidic products from corroding the container. In all instances of sourcing metal packaging for foodstuff, you should always check that the container is food-grade.

Some of our products have an external lacquer or coating. This is usually white. External lacquer on metal products helps protect the metal from environmental elements and can also help with the adhesion of labelling.
