Hey there! As a supplier of C1S food grade cardboard, I often get asked about the maximum temperature this material can withstand. So, let's dive right into it and find out what makes C1S food grade cardboard tick when it comes to heat.
First off, let me give you a quick rundown on what C1S food grade cardboard is. C1S stands for Coated One Side. This type of cardboard has a coating on one side, which gives it a smooth surface that's great for printing and also provides some protection. And of course, it's food grade, meaning it meets the safety standards for coming into contact with food. You can check out more about One Sided Coated Food Grade Cardboard on our website.
Now, the maximum temperature that C1S food grade cardboard can handle depends on a few factors. The main ones are the type of coating, the thickness of the cardboard, and the duration of exposure to heat.
Let's start with the coating. Different coatings have different heat resistance properties. Some coatings are designed to be more heat - resistant than others. For example, a wax - based coating might start to soften at a relatively low temperature, around 40 - 50°C (104 - 122°F). On the other hand, a more advanced polymer coating could withstand temperatures up to 100°C (212°F) or even higher for a short period.
The thickness of the cardboard also plays a big role. Thicker cardboard generally has better heat insulation properties. A thicker C1S food grade cardboard can act as a buffer, slowing down the transfer of heat to the contents inside. If you're using a thin cardboard, say around 0.2 - 0.3 mm, it might start to warp or lose its structural integrity at temperatures above 60 - 70°C (140 - 158°F). But a thicker cardboard, like 0.5 - 1 mm, could hold up better and might be able to handle temperatures up to 80 - 90°C (176 - 194°F) for a short while.
The duration of heat exposure is crucial too. If the cardboard is only exposed to high temperatures for a few seconds, it can handle a much higher temperature than if it's exposed for an extended period. For instance, a quick blast of 120°C (248°F) for a few seconds might not cause too much damage, but leaving it at 80°C (176°F) for an hour could lead to significant changes in the cardboard's properties.
In general, for short - term exposure (less than 10 minutes), a well - coated and moderately thick C1S food grade cardboard can withstand temperatures up to 100 - 120°C (212 - 248°F). But for long - term exposure (more than an hour), it's safer to keep the temperature below 60 - 70°C (140 - 158°F) to ensure the cardboard maintains its integrity and safety for food contact.
If you're looking for a specific type of C1S food grade cardboard that can handle higher temperatures, we also offer OEM C1S Food Grade Cardboard. Our OEM options can be customized with special coatings and thicknesses to meet your exact heat - resistance requirements.
Another product we have is the One Sided Coated Food Grade Cardboard Sheet. These sheets are great for various food packaging applications, and we can work with you to ensure they have the right heat - resistance for your needs.
When it comes to using C1S food grade cardboard in high - temperature situations, there are a few things to keep in mind. First, make sure to test the cardboard under your specific conditions. Every application is different, and what works in one situation might not work in another. Second, consider the overall packaging design. You can use additional insulation materials or design the package in a way that reduces direct heat exposure to the cardboard.
