Avery Waterproof Labels 3-1/3 in x 4 in - 600 Labels, 2-Pack

Our review of these Avery Waterproof Labels finds them best suited for small business shipping, home organization and any project that needs long-lasting, printable mailing labels. The single biggest reason to buy is their combination of Ultrahold permanent adhesive and TrueBlock coverage, which means labels stick reliably to cardboard, glass and metal while fully hiding old text underneath. In testing for everyday mailing and reuse of boxes, the labels also stood up to water, cleaners and handling without smudging or tearing, making them a dependable choice for users who need durable, printable labels.

Key Features

• Waterproof construction: The label material stays intact when submerged and resists scuffing and tearing so printed text remains legible after exposure to moisture.
• Ultrahold permanent adhesive: Adhesive is formulated to stick and stay on surfaces like cardboard, envelopes, plastic, glass and metal, reducing labels peeling off during transit.
• TrueBlock coverage: TrueBlock material completely hides information underneath, allowing boxes and envelopes to be reused without underlying marks showing through.
• Sure Feed technology: Proprietary sheet design improves printer feeding to help prevent misalignments and paper jams when printing large runs of shipping labels.
• Printable with templates: Labels are compatible with thousands of free Avery templates for easy customization and consistent, professional-looking prints.

Who It's For

These labels are ideal for small businesses and home shippers who need a waterproof, heavy-duty label that will survive rough handling and exposure to cleaning solutions. They work well for food-related packaging and any application where temperature and moisture resistance matter because the material resists smudging and can be wiped clean.

Shoppers who primarily need removable or temporary labels should look elsewhere, since the Ultrahold permanent adhesive is designed to stick long term and may damage delicate surfaces if removed. Also, those needing non-rectangular or specialty-shaped labels should confirm compatibility before purchasing.
