Chinaplas 2026 Wrap-Up: Smarter Degassing for Flexible Packaging – SUNBOWN Degassing Valves & Valve Applicator Machines

Chinaplas 2026 (April 21–24, Shanghai) has successfully concluded, once again proving itself as the must-attend event for the global plastics and packaging industry. From sustainable materials to high-speed automation, this year's show highlighted where the future of flexible packaging is headed.

Key Highlights of Chinaplas 2026

• Eco-design & recyclability – Mono-material and bio-based flexible films took center stage.
  
• Lightweighting without compromise – Brands want less material but better protection.
  
• Smart factory integration – Real-time monitoring and fully automated packaging lines were a major attraction.
  
• Extended shelf life – Especially for coffee, pet food, nuts, and fermented products, gas management is now a must-have.
  

As a specialist in one-way degassing technology and valve applicator machines, we saw exactly how our solutions fit into these trends.

Our One-Way Degassing Valves 

We offer a range of proven one-way degassing valves for flexible packaging, with four main models:

• H3 & H4 – Compact, reliable round plastic valves. Ideal for standard coffee bags, pet food pouches, and snack packaging. Excellent sealing performance with a low profile.
  
• H7 & H8 – High-flow versions designed for aggressive degassing needs (e.g., fresh-roasted coffee, fermented vegetables, animal feed). Enhanced pressure release without valve blow-off.
  

All degassing valves are:

• 100% air-tested for leak resistance
  
• Compatible with PE, PP, PET, PLA, and compostable films
  
• Certified for food contact (EU, FDA, REACH)
  

Valve Applicator Machines 

In today's market, two types of degassing valves are most commonly used for flexible packaging:

• Round plastic valves – Typically made of PE material. These are the industry standard for coffee bags, pet food pouches, nuts, snacks, and other dry goods requiring reliable one-way degassing.
  
• Sticker / label-style valves – Adhesive-backed flat valves, often used for applications where a lower profile or a different sealing method is preferred.
  

Because these two valve formats are fundamentally different in structure and application method, they require completely different applicator machines. We offer dedicated solutions for both, ensuring optimal performance and reliability.

Type 1: Applicator Machine for Round Plastic Valves (H3, H4, H7, H8 – PE material)

This machine is designed exclusively for round plastic degassing valves. It applies valves via heat sealing technology.

Key feature – Flexible across different valve sizes within round plastic valves:
Although the machine is specifically built for round plastic valves, it can accommodate different valve diameters (e.g., switching between H3/H4 and H7/H8) by changing simple, interchangeable parts. No need for a completely different machine.

Machine options (with product videos):

• Semi-automatic model DVP-5

Machine type summary for round valves:

• DVP-5 – Semi-automatic, entry-level, ideal for small-to-medium volumes.
  
• DVP-1200 – Fully automatic, single station for higher efficiency.
  
• DVP-2000 – Fully automatic, dual station for maximum output.
  
  
  

Type 2: Applicator Machine for Sticker / Label-Style Degassing Valves

This is a completely different machine designed exclusively for flat, adhesive-backed sticker or label-style degassing valves. It uses a dedicated feeding and placement mechanism optimized for sticker-type valves.

Customization Based on Your Production Needs

Regardless of which valve type you choose, we customize every applicator machine according to:

• Customer production output (pouches per minute)
  
• Valve dimensions (for round plastic valves, we adjust via simple change parts)
  
• Packaging film type (rollstock, pre-made pouches, or inline FFS)
  
• Integration level (standalone semi-auto unit or fully integrated into existing bag-making/pouch lines)
  

We work with you to ensure the machine matches your exact line speed, valve size, and operational workflow.

Looking Ahead – After Chinaplas 2026

The message from Shanghai was clear: flexible packaging is going smarter, greener, and faster. Whether you are packing artisan coffee, bulk pet food, nuts, snacks, or fermented goods, our SUNBOWN one-way degassing valves (H3, H4, H7, H8) and custom applicator machines give you the reliability and scalability you need.
