Why Does PET Strapping Crack or Break? – Jiatuo’s Solution Ensures Durability

SHENZHEN JIATUO Plastic Machinery Co., Ltd. - 30 Years of Excellence in Strapping Production Equipment

With three decades of dedicated expertise in strapping production equipment, Jiatuo Plastic Machinery has consistently driven innovation to provide customers with highly efficient, stable, and competitive strapping production solutions.

In today's increasingly competitive market, we continuously upgrade our technologies and equipment to ensure every machine delivers exceptional quality strapping for our clients.

Many manufacturers face issues with PET strapping cracking or breaking during production or use—but Jiatuo’s machines consistently produce crack-free strapping. So, what causes these failures, and how do we prevent them?

1. Enhanced Filtration System

Problem:
Poor material quality combined with inadequate filtration systems in conventional machines. Standard mesh filters have limited surface area, requiring frequent replacements (often multiple times daily) and failing to fully purify materials, leading to extrusion breaks.

Jiatuo Solution:

• Specialized chemical fiber filter with 2.5-3.5m² filtration area (5-8x larger than standard)
• Integrated oil/dust removal + expanded filtration mesh
• 3-4 day continuous operation without filter changes (vs. daily changes in standard machines)

2. PET Moisture Control

Problem:
PET material degradation due to humidity exposure during production.

Jiatuo Solution:

• Closed-loop dehumidifying drying system

• NIHON NASLON (Japan) desiccant rotor - industry-leading moisture absorption

• Maintains ≤100ppm humidity for consistent material quality

3. Precision Extrusion & Cooling

Problem:
Internal stress points from uneven heating/rapid cooling.

Jiatuo Solution:

• 100CC metering pump + high-precision die flow channel design

• Multi-zone gradual cooling system

• ±1℃ temperature control accuracy

4. Optimized Stretching Process

Problem:
Cracking risks from:

• Excessive stretch ratio (>5x) causing molecular over-alignment

• Inconsistent stretching speeds

Jiatuo Solution:

• PLC-controlled 4-5x stretch ratio

• Pre-heating oven before stretching

• Water-cooled stretching rollers for even temperature distribution

In order to more accurately grasp the market demand, we have established our own PP and PET strapping factory, and continuously optimize the performance of our equipment through actual production. This unique advantage allows us to better understand the needs of our customers, promote continuous breakthroughs in equipment technology, and set higher standards for the industry.

Choosing JIATUO is not only choosing a machine, but also choosing 30 years of professional accumulation and the eternal pursuit of quality.
