Do you frequently send parcels? Would you like to ensure that your shipment reaches its destination intact? Avery Zweckform's weatherproof labels are durable and long-lasting, guaranteed to remain intact no matter the weather conditions. Smudged addresses look unprofessional and are difficult for postal services to read. These labels are water- and dirt-resistant, tear-proof, and resistant to UV light and temperature, ensuring that your address remains legible at all times. If you use polyethylene or Tyvek envelopes, these labels are the perfect complement.
