Avery Waterproof Labels Ultrahold Adhesive 5.5 x 8.5 in - Durable

Our review of these Avery Waterproof Labels finds them best for anyone who needs durable, permanent labeling that survives moisture and frequent handling. The single biggest reason to buy is the combination of waterproof construction and Ultrahold permanent adhesive, which lets these labels stay intact when submerged, resist household cleaners, and hide underlying text with TrueBlock material. They are specifically made for laser printers, so people needing inkjet compatibility should look elsewhere.

Key Features

• Waterproof: The label material remains intact when completely submerged and survives exposure to water without delaminating.
• Ultrahold adhesive: A permanent adhesive formulation is designed to stick to cardboard, plastic, glass, metal and more for longer than basic labels.
• TrueBlock material: The opaque surface reliably covers old text and designs so reused boxes and packages look clean and professional.
• Chemical resistant: Labels tolerate common household cleaners and resist smudging when wiped, making them practical for food and product applications.
• Laser printer only: Optimized for laser printing with sharp print quality and grade A barcode readability when printed correctly on a laser printer.
• Food contact acceptable: Temperature resistant and acceptable for food contact, which broadens use to food packaging and soap labels.

Who It's For

These labels suit small businesses, shipping operations, and crafters who print with laser printers and need long-lasting, waterproof stickers for product packaging, reuse of boxes, or outdoor applications. The TrueBlock opacity also helps users who refurbish or repurpose packaging and need to fully cover prior markings.

They are not appropriate for inkjet users or anyone requiring removable or repositionable labels, since the sheets use a permanent Ultrahold adhesive and are explicitly compatible only with laser printers.
