If you are using Pressure Sensitive BOPP, there are two adhesives that dominate the market -

Water Based "Acrylic" Adhesive

This is a very popular, environmentally friendly adhesive, that offers -

•  Superior Clarity - will not yellow over time
• Can be applied from 32F up to 120F, once on the box offers good freezer performance
• Has superior "Fiber Tear"  performance when pulled off box
• Rohm & Haas offers the best Acrylic Adhesive and is available on Qspac's PA series

Hot Melt / Synthetic Rugger

• Good choice for high speed machine application
• Will yellow with UV & Oxygen exposure
• Very good internal strength for springy box flaps
• Shouldn't be applied below 40F
