Problem: Leakage and absorbency are disadvantages of paper coffee cups

Paper cups are common items at coffee shops, especially paper cups used for brewing coffee. However, paper coffee cups are often prone to leakage and absorbency due to their paper composition. This affects the user experience and causes coffee wastage.

Specifically, the issues of leakage and absorbency in paper coffee cups include:

• Coffee liquid soaks through the cup walls, wetting the holder’s hands.
• Drinks spill out when moving or bumping the paper cups.
• The paper becomes damp and soft over time from absorbing liquids.
• Coffee is wasted due to leaking and spilling out.

Therefore, finding ways to increase durability and water resistance is an urgent issue for coffee shops using paper cups to brew coffee.

Approach: Solutions to increase durability and water resistance of cups

To improve the durability and water resistance of paper coffee cups, business owners can apply the following solutions:

1. Use specialized paper types

There are many types of paper with good water resistance such as:

• Couche paper: Smooth, thick, high water resistance.
• SBS paper: Has a smooth glossy coating, good water repellency.
• PE-coated paper: Coated with a PE plastic layer for effective waterproofing.

These types of paper are suitable for making coffee cups to prevent spills or absorption.

2. Increase cup thickness

The thicker the paper cup, the better its water resistance. Cups with 220 - 250 grams/sqm thickness are recommended.

3. Apply embossed wave technology

Embossed wave technology enhances paper elasticity and water resistance. This is a technology that should be applied.

4. Design cups with narrow mouths and curved rims

Narrow mouths and curved rims fit snugly against the lips, minimizing spills and overflows.

5. Coat interior with a wax or plastic layer

The thin wax or plastic coating enhances the cup’s tightness and water resistance.

The above solutions will help paper coffee cups gain better durability and water resistance, providing a good user experience.

Solution: Benefits of water-resistant paper coffee cups

By applying solutions to enhance durability and water resistance, paper coffee cups will provide many benefits for both coffee shops and customers:

• Minimize spills, leaks, and wet hands when holding cups.
• Better heat resistance, not becoming soft or punctured when containing hot liquids.
• Save costs by reducing coffee wastage from spills and leaks.
• Improve heat retention and insulation for drinks.
• Enhance customer experience when using the product.
• Create an eco-friendly impression by using paper instead of plastic cups.

Therefore, investing in upgrading paper coffee cup quality is essential for coffee shops to better serve customers, save costs, and increase revenue.
