Hey there! As a paper cup raw material supplier, I often get asked if there are any differences in paper cup raw materials for hot and cold drinks. Well, you bet there are! In this blog, I'm gonna break down these differences and give you the lowdown on what makes each type of raw material unique.
Let's start with the basics. Paper cups are a staple in our daily lives, whether we're grabbing a morning coffee or a refreshing soda. But not all paper cups are created equal, especially when it comes to the raw materials used for hot and cold drinks.
Raw Materials for Cold Drink Paper Cups
When it comes to cold drinks, the main concern is preventing condensation from making the cup soggy and falling apart. That's why the raw materials for cold drink paper cups are designed to be moisture-resistant.
One of the most common raw materials for cold drink paper cups is Paper Cup Raw Cardboard. This cardboard is typically made from virgin wood pulp, which gives it strength and durability. It's also coated with a thin layer of polyethylene (PE) on the inside. The PE coating acts as a moisture barrier, preventing the cold liquid from seeping into the cardboard and making it weak.
The PE coating on cold drink paper cups is usually around 10-20 microns thick. This thickness is sufficient to keep the cup dry and sturdy, even when filled with ice-cold beverages. Another advantage of the PE coating is that it's food-grade, which means it's safe to come into contact with the drinks we consume.
In addition to the PE coating, some cold drink paper cups may also have a printed outer layer. This outer layer can be used for branding, advertising, or just to make the cup look more appealing. The printing on the outer layer is usually done using food-safe inks, so there's no risk of the ink contaminating the drink.
Raw Materials for Hot Drink Paper Cups
Hot drink paper cups have different requirements compared to cold drink paper cups. The main challenge here is to withstand high temperatures without melting or releasing harmful chemicals.
Just like cold drink paper cups, hot drink paper cups also use Paper Cup Raw Cardboard as the base material. However, the coating used on hot drink paper cups is different. Instead of a PE coating, hot drink paper cups are often coated with a special type of polymer called polylactic acid (PLA) or a combination of PE and other heat-resistant polymers.
PLA is a biodegradable and compostable polymer made from renewable resources such as corn starch or sugarcane. It has excellent heat resistance properties, which means it can withstand temperatures up to 100°C (212°F) without melting or deforming. This makes it an ideal coating material for hot drink paper cups.
The thickness of the coating on hot drink paper cups is usually a bit thicker than that on cold drink paper cups, around 20-30 microns. This extra thickness helps to provide better insulation and heat resistance.
Another important consideration for hot drink paper cups is the strength of the cardboard. Since hot drinks are often served in larger cups and can be quite heavy, the cardboard needs to be strong enough to support the weight of the liquid without collapsing. That's why hot drink paper cups may use a thicker or more dense cardboard compared to cold drink paper cups.
Other Factors to Consider
Apart from the coating and the cardboard, there are a few other factors that can affect the performance of paper cups for hot and cold drinks.
One of these factors is the shape and design of the cup. Cold drink paper cups are often designed with a wider opening and a more tapered shape, which makes it easier to drink from and also helps to prevent spills. Hot drink paper cups, on the other hand, may have a narrower opening and a more straight-sided design to help retain heat and reduce the risk of burns.
Another factor is the insulation properties of the cup. For hot drinks, it's important to have good insulation to keep the drink hot for as long as possible. Some hot drink paper cups may have an extra layer of insulation, such as a double-wall design or a foam layer, to help achieve this. Cold drink paper cups may also have some insulation properties to keep the drink cold, but it's not as critical as for hot drinks.
