Liquiguard
Effective protection against moisture and oil absorption
Liquiguard is a water and oil resistant coating that has been developed for various industries. Typical applications are for wet and oily products such as meat, fish, fruit, vegetables and flowers. It is used successfully in moving automotive and industrial components that are greasy. Liquiguard offers excellent resistance to abrasion and is used for protecting plastic components during transit. Due to its shiny surface it is used for the packaging of powders where the containers need to be wiped clean before shipping.
| Save Money | By using Liquiguard there is no need to pack products in plastic bags or to utilise polylined or waxed board. |
| Save Time | Using Liquiguard coated board means that goods can be loaded direct into your boxes without a secondary packaging operation - just load and seal. |
Environmentally Friendly |
The materials used to manufacture Liquiguard coating are acrylic emulsions which are fully biodegradable and recyclable on normal paper materials. Liquiguard is FDA approved for direct contact with food but care should be taken when it is applied to test liners as we cannot guarantee the make-up of the test liner. It is readily accepted at paper mills who prefer it over polylined or wax impregnated board, both of which are environmentally unfriendly. |
| Safe | The emulsion used does not contain any dangerous substances and the material can be handled without the need for any protective clothing. |
Liquiguard is a blended waterbourne acrylic lattice, which creates a totally non-hazardous inert translucent film when coated and dried onto paper or board. Containing only water as the carrier system with no halogenated compounds or hydrocarbon co-solvents.
Liquiguard requires special pva adhesive for cold gluing or a hot melt adhesive about which we can advise you. Liquiguard is excellent for storing frozen foods and will not separate from the liner and can also be used for 'cook in the box' products.
We offer short runs of Liquiguard so why take risks with your products?
Our minimum run is normally 500 sq. metres onto any fluted board grade. The minimum sheet size is 250 x 600 mm and the maximum 1500 x 4000 mm.
Conversion
Best results are obtained on pure kraft or white top kraft liners but test liners can be used on non-food applications. Liquiguard can be applied to either one or both sides of corrugated board and gives a clear finish but tends to darken the underlying paper. It can normally be overprinted with water based Flexographic inks or, alternatively, can be used over the top of our Spectrumcoat coloured board or other pre-printed board to give an enhanced point of sale product.
Specification
The endurance of water and oil resistant board is normally measured by the Cobb and 3M tests. Typical test results obtained on our Liquiguard material are below:
Cobb: 3 minutes = 2.0 30 minutes = 10.0 3M Kit Test: = >12
Cobb Test. This determines water absorption. There are three exposure times used: 1 minute, 3 minutes and 30 minutes. The test involves a known volume of water ( 100 ml ) being poured onto a specific area of the board's surface ( 100 cm2 ). The board is weighed before and after the exposure and the difference between the two can then be expressed as the weight per unit area of water absorbed in that given time, so the lower the Cobb value the better the result.
3M Kit Test. This involves putting five separate drops of various solvents onto the boards surface and inspecting it after 15 seconds to see if any pinholes appear (visible as dark specks). The solutions range from a thick vegetable oil to thinner substances like white spirit. Each solution is numbered up to a maximum of 12 and the higher the number achieved the more resilient the surface.
