What do you need for your products? Waterproof or water-resistance?
If you sell health and beauty products, outdoor items, food and beverages, or other items that might come into contact with moisture or water, you need labels that will remain legible and stay adhered to your products. In this article, we will discuss the waterproof vs. water-resistant labels, the testing they go through, and what are the best labels for your products.
All Avery labels go through rigorous testing before they go to market. Our research and development team is constantly testing adhesives, materials, and printing so that we can provide our customers with the best possible label performance.
More than 100 individual tests are performed on all of our label materials to make sure they meet our customers’ needs. From oil and fade resistance to tearing and abrasions, all of our products are tested to the highest industry standards.
Our waterproof labels and water-resistant labels are tested on both High Surface Energy (HSE) items and Low Surface Energy (LSE) items. Surface energy, in simple terms, is how much the adhesive and the surface repel or attract each other.
The lower the surface energy, the harder it is for label adhesives to adhere. Examples of LSE items would be polypropylene, polyethylene, PVC, acrylic, and PTFE fluoropolymer.
For HSE items, the opposite is true and the labels will stick easier. Examples of HSE items are stainless steel, copper, tin, aluminum, glass, and PET. Avery labels are tested on stainless steel (HSE) and HDPE plastic (LSE) to assure they will stick and stay during water testing.
Avery water-resistant labels must pass testing based on the Electronics IP44 IEC testing. The testing rates a product’s ability to protect against the infiltration of water, dust, or other foreign objects.
We test printed labels on both HSE and LSE products. The printed label samples are sprayed with water and vigorously rubbed more than 10 times with a cotton swab. If there is no ink bleed or smearing, the labels are deemed water-resistant. All of our water-resistant labels are also safe for use in standard refrigerators and freezers.
Use water-resistant labels on products that may get splashed, rinsed, or wiped off but that won’t be submerged in water. Examples of this would be things like health and beauty products, or food items that won’t be iced down are great uses for our water-resistant labels.
Avery waterproof labels are tested following the standards of ISO 6425, which was created in 1996 for underwater diving watches.
We fully submerge a product with a printed label in water for at least seven days. The product and label are then removed from the water, and the printed label is rubbed vigorously more than 10 times with a cotton swab to check for ink smears and bleeding.
We test our label adhesives at the same time on both HSE and LSE containers. All of our waterproof materials are also safe for use in standard refrigerators and freezers.
Use waterproof labels on products that will get submerged in ice or water, or that are exposed to extreme temperatures or outdoor environments. They’re great for bath and body products, beverages, outdoor plants, and accessories, or any item that you want your label to stay legible and adhered to.
