A few things to look out for

Tips

Which backing material?

Glassine paper The economic choice – available in white honey. Has limited printing quality on the reverse side.
Kraft paper Usually for sheet labels. With certain grades, kraft backings can have high-quality printing on the reverse side.
Filmic The ultimate choice for high-speed labels, clarity of clear labels and the mirror finish of metallised labels. Has limited printing quality on the reverse side.

Hints

While almost any label can be applied to any product, some face materials and adhesives are simply better suited for certain end-uses. The following hints explain why some materials may be the optimal choice for your end-use.

Beware of
Clear films - for food and beverage labelling to be kept cold - can appear yellowish and hazy due to the special adhesive required for low temperature adhesion.
Clarity - a filmic backing material is required to maintain clarity, smoothness and a mirror appearance when using metallised films for food labelling at room temperatures, personal care labels and home care labels.
Flexo and letterpress printing - these methods may not be able to achieve the desired quality when printing on textured papers for wine. Offset litho produces the best results.
White and clear films - these aren’t suitable if using a wash-off adhesive.
Thin white film for personal and home care labels may have reduced opacity when used on dark coloured containers. This could cause the film to lose its brilliance.
Thin paper used on pharmaceutical products can result in reduced opacity.
Large amounts of ink on clear films for pharmaceutical use, can compromise the performance of labels - especially on tubes and containers with a small diameter.
