Paper Soup Bowl Forming Solution

Hot soup packaging presents strict requirements for paper bowls in terms of heat resistance, leak prevention, sealing compatibility, and structural strength. Compared to cold food bowls, soup bowls must be specially configured in paper weight, coating, and structure to prevent softening, leaking, or deformation during heating, handling, or delivery.

1. Application Scenarios

Dine-in or takeaway packaging for Chinese and Western hot soups (e.g., chicken soup, borscht, porridge, stew)

Fast food restaurants, bento shops, noodle bars

Supermarket ready-to-eat soup sections (microwaveable packaging)

Food delivery platforms specializing in soup

2. Capacity & Paper Weight Recommendations

Soup bowls are typically 12oz–32oz large capacity, requiring high grammage double PE-coated paper for heat and moisture resistance:

✅ Double-sided PE-coated paper is essential to ensure heat resistance, leak prevention, and protection against steam and liquid saturation. Secure lid pairing is recommended for hot food delivery use.

3. Bowl Structure & Functional Design

Structure: High-strength single-wall with thickened rolled rim to improve pressure resistance and lid sealing

Body Shape: Wide-mouth for easy access and reheating; bowl depth can be adjusted according to soup contents

Bottom: Reinforced bottom sealing to prevent leakage during prolonged liquid contact

Lid Compatibility: Vented paper lids or spill-proof PP lids are recommended for safer transport and better user experience

4. Summary

Recommended Capacity: 12oz–32oz for individual and shared serving sizes

Structure: Thickened single-wall paper bowl with strong lid compatibility

Paper Configuration: 280–330gsm with double PE coating for hot liquids

Key Benefits: Anti-scald, leak-proof, durable under high-temperature and delivery conditions

By optimizing the structure and matching raw paper configuration, soup bowls can achieve higher forming success rates and safer usage, meeting food packaging requirements for modern takeout and retail applications.

Based on our years of experience in paper bowl forming machinery and product design, this solution offers practical, safe, and scalable recommendations for manufacturing paper soup bowls.
