Surfaces Must Be Clean
- All pressure sensitive self-adhesive labels should be applied to reasonable clean, smooth surfaces for best adhesion.
- Dust, loose fibres, oil, grease, wax or other surface agents interfere or prevent proper adhesion of labels.
- It is advisable to wipe surfaces clean and dry before applying the labels.
- The labels should be applied with a positive pressure over their entire surface. This is particularly important with the tamper proof labels with security cuts.
Handle Labels Carefully
- Natural oils in the skin can "kill" the tack of the adhesive. Personnel using the labels should minimise handling them after removing the label from the backing paper. Monarch Labellers are designed to used to print and apply the labels. Printing the label and then applying by hand should be avoided.
Be Sure the Surface Will Take the Label
- Some moulded materials such as rubber, plastic items and synthetics will not accept any self-adhesive labels because the surfaces and adhesives are not compatible. These items are coated with silicones or other mould release agents. Waxed surfaces are also in this category
Pre-Test For Possible Merchandise Damage
- Various materials may not be compatible with self-adhesive labels and some damage may occur.
- A label should be tested on each new type of article or finish before general usage as some merchandise can be affected by the adhesive or ink on the labels. If such conditions do exist, we do not recommend the use of the labels. No guarantee can be given covering such usage
- On certain types of plastic merchandise, and on leather, it is sometimes possible for marking and pre-print inks to migrate through the labels and damage the merchandise. The transfer of inks is caused by plasticisers found in the plastic materials. As the plasticisers migrate through the gum into the label, they contact the inks and transfer them to the plastic. The ink does not just stop at the surface of the plastic but penetrates the full depth of the material. When inks containing dyes come into contact with plastic they will permanently colour the plastic material. Vinyl plastic materials are quite easily affected. Wallets, place mats, artificial fruit, garments, etc, could all be stained or damaged. The degree of possible damage will depend on the time the label is on the merchandise, how much ink has been used on the label and the amount of plasticisers in the item to be labelled.
- Do not apply self adhesive labels directly to timber crafts and furniture. The timber will darken under sun and fluorescent lights over time. When the label is removed there will be a lighter area where the label was applied.
Allow Time For Adhesion
- On many surfaces, full adhesion will not occur imediately. It is advisable to allow up to 24 hours for full adhesion to develop after properly applying the label. This time will depend on the type of adhesive, climatic conditions and the surface to which the label is applied.
