Durable Custom Labels That Don’t Melt or Burn Under Heat

For the product’s security and customers’ attention, packaging plays a crucial role in standing out in this competitive market. Custom labels help to enhance a product’s presentation and brand identity. These are also used to convey all usage instructions and fulfill all legal requirements. If you have labels that showcase melting and burning in extreme weather conditions, then you have to be careful to select the right materials and printing techniques. This complete guide will cover the best weatherproof custom labels and the best practices for creating custom labels that dont melt or burn. So, let us begin!

Significance of Durable Custom Labels

Custom labels are beyond just decorative elements, and they are also useful, serving as promotional yet informational tools. A durable label:

Protects the information printed on the product against damage

With complete compliance, it provides you with compliant labeling needs

Helps consumers better identify your brand.

Work well against moisture, UV sunlight, and heat.

Unfortunately, standard types of labels are not conducive to harsh conditions. And they often suffer smudging, melting, peeling, or burning. This results in spoiled products, damaged brand image, or costly re-labelling.

What Causes Labels To Melt And Burn?

Labels are made from paper, polyester, or vinyl substrates and different ink types. Some labels that are vulnerable to heat sources and are capable of: 

Melting (low-melt adhesive or plastics)

Burning (open flame or excessive heat)

Breakdown or fading (when exposed to UV)

To avoid these situations, confirm the suitability of materials and printing processes.

Choosing the Right Materials for Custom Labels That Don’t Melt or Burn

Polyester (PET) Labels

Polyester labels are the sturdiest labels available for the harshest environments. They are well-known for their heat, chemicals, UV rays, or tear resistance. 

Heat Resistance

These labels can withstand temperatures of up to 300°F (149°C). They don’t melt, bend, or deform. Excellent for situations where applications might be in proximity to ovens or factory machinery, or in hot conditions for storage.

UV Stability

They will not fade with exposure to the sun, even after long periods in direct sunlight, nor will they lose readability over the years; this is especially important for outdoor applications or products exposed to UV light.

Chemical and Tear Resistance

They are inert polyester materials that are resistant to most chemicals, oils, and solvents. Their inherent toughness allows them to offer a high degree of tear resistance when handled and worn. 

Applications

These properties make them suitable for industrial labels, food wrapping applications, and for use on spice jars in warm or outside environments. And for any application where durability is required.

Vinyl Labels

This material can be used in outdoor and industrial applications. Because of its moisture as well as chemical, or moderate heat resistance. 

Waterproof and Chemical Resistance

Vinyl labels are waterproof and oil-resistant.  They effectively resist many cleaning agents. So these labels can be used for any product that is washed regularly or will come in contact with moisture. 

Temperature Tolerance

Up to about 180°F (82°C), these labels can go well against temperature without distortion or losing adhesion. You can use these in several situations involving heat, including beverage containers transported in warm conditions or spice containers stored near heat. 

Flexibility and Durability

Vinyl is flexible. It allows it to wrap around curved surfaces, and tough, which gives it resistance to scratches, tears, and abrasions. 

Applications

These weatherproof custom labels are typically found on outdoor signage, industrial containers, beverage and condiment bottles, and spice jars, where waterproof and chemical labeling is required. 

Polypropylene Labels

These thermoplastic polymers are ones that offer a perfect balance of cost and durability. These labels are suited for a number of labelling functions. 

Chemical Resistance

Polypropylene labels show high resistance to many polar and basic solvents, as well as acidic solvents. They offer an attractive choice for labeling products that may come into contact with cleaning agents or chemicals.

Moderate Heat Resistance

The polypropylene has been able to endure low amounts of temperature exposure or cold storage. Hence, this property allows the use of custom spice labels and food labels in low-temperature and cold-storage environments. 

Flexibility and Impact Resistance

They apply to curved surfaces due to their flexibility and are less brittle than others; they resist cracking. 

Applications

They are commonly found being used in food packaging and spice containers. Perfect, too, for labels that endure mild heat or refrigeration.

High-Temperature Labels 

Labels that are made from polyimide and specialty films can work well in extreme conditions when regular materials won’t suffice. 

Extreme Heat Tolerance

They are capable of withstanding a temperature of 500°F (260°C). High-temperature labels are those custom labels that neither melt nor burn, nor lose their adhesive properties. 

Applications

You can use these labels in industrial machinery, automotive manufacturing, aerospace, or other demanding conditions where ambient heat is common. 

Overkill for Retail

It provides incomparable heat resistance using these labels. For most food or retail uses, these can also be spice labels used under severe industrial processing or oven conditions.

Printing Techniques for Durable Custom Labels

After material selection, you should choose the right printing method along with the inks to get custom labels. Consider the following options: 

1. UV-Curable Inks

These inks are cured with UV light. UV-curable inks offer excellent UV and abrasion resistance. You can use these inks for weatherproof labels or for outdoor use. Perfect for printing vinyl or polyester substrates. 

2. Laser Printing

This printing option creates sharp and strong images. These images will be smudge-resistant and fade-resistant. Additionally, laser printing develops weatherproof labels that stand up to environmental factors.

3. Screen Printing

When it comes to printing larger batches, utilizing screen printing with special inks produces very durable labels. Screen printing is typically used for industrial applications that can resist steam or heat.

4. Thermal Transfer Printing

In this printing technique, ribbons can be used to transfer ink to the label surface. With resin-based ribbons, you can produce highly weatherproof labels. As a result, your labels will become scratch-resistant or heat-resistant.

Best Tips for Designing Labels That Withstand Environmental Stress

The following are principles to incorporate when designing labels that can withstand environmental conditions. Here are design elements to keep in mind:

Using high-contrast colors can assist you with readability in your environment. 

Laminations or some clear overcoat will protect your surface from scrapes and UV damage.

Stay away from inks and adhesives that may be affected by wet or heated environmental conditions. 

Think about using larger font sizes, along with spacing, to help highlight important information that is easy to read for your audience. 

Be sure you have a barcode or QR Code. Consider adding an overlap to your label to minimize wear.

Special Considerations For Spice Labels: 

UV light-resistant inks or durable materials make a protective layer. Go with an adhesive designed to limit the risks of labels peeling off. And always choose high-temperature resistant labels. So they can be easily stored in an oven or near heat sources.

Practical Tips for Producing Custom Labels That Don’t Melt or Burn

Use these tips to develop custom labels that don’t melt or burn. 

Before mass production, expose your labels to external conditions and see how they perform in forums other than your office.

Select suppliers like Packaging Bee. We specialize in weather-proof or high-heat media for labels.

Consider eco-friendly choices that conform to typical industrial durability and competence standards.

For products that experience temperature changes, make sure your adhesives continue to hold. 

Store your printed labels out of any direct sunlight or moisture until ready to apply.
