From material choice
to the finished bottle.
Separate pressure-sensitive adhesive cold flow and edge ooze from bleed-through by checking polymer rheology, coat weight, slitting rewind tension, and warehouse storage climate.
Separate label application and service temperatures, then check condensation, first contact and label stiffness to prevent cold-bottle edge flagging.
Compare BOPP and PE for waterproof bottle labels, separating film flexibility, adhesive application temperature and retention in condensation or ice water.
Record cold-service retention and the approved bottle-washing route separately when specifying wash-off labels for returnable beverage bottles.
Separate a liner pop-up edge from a label that leaves the bottle, and leave material, dwell time and residue blank until a sample shows them.
