Avery Printable Shipping Labels 3-1/3" x 4" White Sure Feed, 600 ct — UltraHold Adhesive & TrueBlock

Avery 3-1/3" x 4" Sure Feed shipping labels (5164) are bright white, laser-compatible address labels with UltraHold adhesive and TrueBlock coverage for 600 reliable, professional-quality prints.

These sheets are built for high-volume mailers, small businesses, and crafters who need clean, consistent labels that feed smoothly through laser printers and hide previous markings. The sheets pair a permanent Ultrahold glue with Avery's Sure Feed system to reduce misfeeds, while TrueBlock lets you completely cover old labels, barcodes, or shipping marks so reused boxes look new. They work with Avery’s free templates and mail-merge tools, so personalizing or batch-printing addresses, logos, or designs is fast and accurate.

How do these labels prevent printer jams and smudges?

Avery’s Sure Feed technology helps each label sheet move consistently through laser printers, minimizing misfeeds and paper jams. The sheets are optimized for toner-based machines, so toner adheres cleanly without smearing or faint areas.

• Laser-optimized paper reduces toner transfer issues
• Sure Feed sheet design promotes even printer pickup and alignment
• Bright white surface yields crisp text and vivid color prints
• Works with most office and production laser printers

Can I cover up old shipping information or reuse boxes?

Yes — TrueBlock technology is formulated to fully block out underlying text, barcodes, and labels so you can give used cartons a fresh appearance. Apply the 3-1/3" x 4" rectangle labels over old marks for a neat, professional look that prevents previous details from showing through.

• Opaque layer hides prior addresses and labels completely
• Use on corrugated cardboard, envelopes and assorted packaging
• Helps maintain a clean brand presentation when reusing boxes
• Useful for returns, resale, or repurposed shipments

What surfaces and applications will the UltraHold adhesive handle?

UltraHold permanent adhesive is formulated to stick securely to many common shipping and storage surfaces so labels stay put during transit. These labels adhere well to cardboard, paper, plastic, glass, and metal, making them versatile for mailing, returns, and product labeling.

• Strong, long-lasting bond on cardboard and paper
• Reliable adhesion to plastic, glass, tin, and metal containers
• Suitable for long shipments and storage without lifting or curling
• Works for product tags, jar labels, and party favors as well

How easy is it to customize and print these labels?

Printing and customizing is straightforward: use Avery’s free templates and design tools or set up a mail-merge for bulk addresses. You can add logos, color blocks, or variable address fields and produce consistent results across all 600 labels in the pack.

• Free online templates match the 3-1/3" x 4" layout exactly
• Mail-merge support for batch address printing from spreadsheets
• Design tools let you add images, barcodes, or return labels
• Handwriting or pens also work for small custom jobs
