Custom cup sealing film custom has become a required packaging solution for modern beverage brands, especially in the bubble tea, juice, coffee, and dairy drink industries. Businesses today need sealing film that is safe, durable, highly printable, and fully compatible with cup sealing machines. This guide explains everything you need to know before ordering cup sealing film custom, including film materials, printing options, roll sizes, sealing performance, machine compatibility, and food-grade standards.

What Is Custom Cup Sealing Film?

Custom cup sealing film is a heat-seal plastic film roll used to seal PP, PET, and paper cups in bubble tea shops, juice bars, and beverage factories. When heated by a sealing machine, the film bonds tightly to the cup rim, creating a tamper-proof, leak-proof, and hygienic seal.
Businesses choose custom cup sealing film because it allows them to add brand logos, artwork, product details, and QR codes—turning every drink cup into a marketing platform.
Custom sealing film is available in multiple materials, thicknesses, widths, and printing options based on cup type, sealing temperature, and machine requirements.

Why Businesses Choose Custom Cup Sealing Film

 
Businesses increasingly prefer custom cup sealing film because it elevates packaging quality, hygiene, branding, and sealing performance.
Enhanced Hygiene and Safety
Sealing film covers the entire cup opening, preventing external contamination from dust, bacteria, and environmental exposure.
Branding and Marketing Advantages
Using custom printed sealing film helps businesses promote their identity across every cup. Creative designs attract customers and boost brand recognition.
Leak-Proof & Secure Sealing
Properly matched film ensures strong, airtight sealing that prevents leaks during takeaway or delivery.
Cost-Efficient Packaging
Compared with snap-on lids, sealing film is cheaper, lighter, easier to store, and faster in sealing operations.
Machine Compatibility
Most machines support PP, PET, or PE films, ensuring smooth operation, reduced errors, and better sealing quality.

Types of Cup Sealing Film Materials

Cup sealing films are primarily made from PP, PET, or PE. Each material delivers different thermal resistance, clarity, and sealing strength.

Material	Key Features	Best For
PP (Polypropylene)	High clarity, strong heat resistance, durable	PP cups, bubble tea, milk tea
PET (Polyester)	Ultra-clear, premium printing, high tensile strength	Juices, iced coffee, premium beverages
PE (Polyethylene)	Soft, flexible, low sealing temperature	Paper cups, dairy, yogurt

Selecting the correct material is essential when choosing cup sealing film material types or PP/PET/PE sealing film.

PP, PE, PET: Which Material Is Best for Your Cup?

PP Film for PP Cups
PP film is the most widely used sealing film for bubble tea, milk tea, and hot beverages.
PET Film for PET Cups
PET film provides crystal-clear transparency and sharp printing, ideal for colorful cold drinks.
PE Film for Paper Cups
PE film seals at low temperatures, ideal for yogurt cups, dairy drinks, and paper cup products.
A mismatch between film and cup can cause leakage, film tearing, or poor adhesion.

How to Choose the Right Film for Beverage Shops

To ensure proper sealing performance, always follow these steps:

1. Match Film to Cup Material

  • PP cups → PP sealing film
  • PET cups → PET sealing film
  • Paper cups → PE sealing film
This avoids sealing issues when using sealing film for pp cups, sealing film for paper cups, or PET film cups.

2. Choose the Right Thickness

High-volume and delivery shops benefit from 80–90 μm.

3. Confirm Cup Sealing Machine Film Compatibility

This includes:
  • Roll width
  • Thickness
  • Core diameter
  • Sealing temperature

4. Ensure Food-Grade Safety

Only use food-grade sealing film that meets global standards.

5. Use Custom Printing for Branding

Branded cup sealing film adds professional quality and boosts repeat customers.

Food-Grade Safety Standards

High-quality sealing film must meet strict testing requirements:
  • FDA food-contact approval
  • EU 10/2011 certification
  • ISO 22000
  • LFGB compliance
  • BPA-free materials
These are essential for safe plastic seal film, plastic cup sealing film, and heat sealing packaging film for beverages.

Heat Sealing Performance & Temperature Requirements

Different materials require different sealing temperatures:

PP Sealing Film

  • Sealing temperature: 170°C–200°C
  • Suitable for hot and cold drinks
  • Strong sealing strength
