Why is "Waterproofing" More Important Than You Think?
For many businesses, especially:
-
Online stores
-
Homemade product brands
-
Beverage businesses
-
Fruit exporters (e.g., Durian packing houses)
-
Chilled / Frozen products
Stickers don't just encounter water;
they face:
-
Accumulated humidity
-
Condensation from refrigerators
-
Moisture from consumers' hands
-
Friction during transport
If you choose the wrong sticker, your brand image will suffer immediately.
What Does "Waterproof" Actually Mean?
A truly waterproof sticker means the surface material does not absorb water, the printing ink does not dissolve when wet, and the adhesive does not degrade in humid environments. It is not just glossy-coated paper labeled as waterproof.
How to Test if a Sticker is "Truly Waterproof"
Test by soaking it in water for 5–10 minutes, then wipe it gently to see if the color fades. Leave it in a refrigerator for 24 hours; if the adhesive remains firm and the colors don't fade, it meets the standard.
Check the Surface Material First (The Most Important Part)
Truly "Waterproof" Materials
-
PP (Polypropylene)
-
PVC
These materials are "plastic films,"
meaning water cannot penetrate the material itself.
"Non-Waterproof" Materials
-
Standard paper stickers
-
Coated art paper
Even with a glossy coating, water can still seep in through the die-cut edges.
Sticker Adhesive is More Critical Than You Imagine
Fruit exporters and frozen food businesses often face these issues:
-
Stickers peeling off from fruit stems or skins.
-
Adhesive failure due to extreme cold.
There are several types of adhesives:
-
Acrylic adhesive
-
Rubber adhesive
-
Cold-resistant adhesive
If applying stickers to chilled produce, you should inform the printing house to select the appropriate adhesive.
What Does Coating Help With?
Coatings such as:
-
Matte Lamination
-
Glossy Lamination
-
UV Coating
Help to increase:
-
Scratch resistance
-
Aesthetic glossiness
-
Product lifespan
However, coating alone does not turn regular paper into 100% waterproof material.
How "Laminated PP Stickers" From Our Printing House Are Different From Standard Ones
The stickers we produce are PP (Polypropylene) Stickers with Lamination. This is a waterproof film material that does not absorb water, and the additional lamination enhances scratch resistance. It is perfect for online businesses, chilled goods, and fruit exporters who need actual durability—not just "waterproof" as a marketing buzzword.
Why PP (Polypropylene)?
PP stickers are plastic films, not paper, giving them the following properties:
-
Completely waterproof
-
Will not swell when exposed to moisture
-
Resistant to refrigerator condensation
-
Fade-resistant colors
This differs from coated paper stickers that may look identical but will swell and peel at the edges when exposed to water.
FAQ: Common Questions About Waterproof and Cold-Resistant Stickers
1. Is glossy coating considered waterproof?
Not necessarily; it depends on the surface material (substrate).
2. Can paper stickers be used on water bottles?
Not recommended, as they may swell and fall off.
3. Is UV ink better?
Yes, it is excellent for waterproofing and outdoor applications.
4. Which adhesive is best for fruit?
Adhesives that are highly resistant to cold and moisture.
5. Are die-cut stickers more expensive?
Slightly, due to the die-cut setting process.
