Have you ever wondered how strong, reliable plastic packing straps are made from old soda bottles? It’s a fantastic process of recycling and smart engineering. For businesses that make these straps, one machine makes all the difference in creating a top-quality product: the Infrared Rotary Dryer (also known as an Infrared Crystal Dryer).

Lianda Machinery has focused on plastic recycling equipment for over two decades. We know you need a solution that hits the mark. The answer is our Infrared Rotary Dryer. Engineered specifically to solve the core drying challenge in PET strap production, it delivers unparalleled stability and efficiency through simple design—your key to superior product quality and market competitiveness.

What is a PET Packing Strap Line?

First, let’s break it down. This production line turns recycled PET plastic (like crushed water or soda bottles) into those strong straps used to secure boxes on pallets. A key part of this line is drying the plastic flakes perfectly before they are melted and formed into straps. If the flakes are too wet, the final straps can be weak and unreliable. This is where our star player comes in.

Meet the Super-Dryer: The Infrared Rotary Dryer

Imagine a dryer that works not just with hot air, but with precise infrared energy. Our Infrared Rotary Dryer is like a magic box that prepares PET flakes in record time. Here’s how it works in a simple PET Packing Strap Line:

1. Feeding: Recycled PET bottle flakes are sucked into the dryer using a vacuum feeder.

2. The Magic Happens: Inside the Infrared Rotary Dryer, the flakes are gently tumbled while being heated by infrared energy. This does two crucial things at once: it dries AND crystallizes the plastic.

3. Result: In just 20 minutes, the flakes come out perfectly prepared. They are super dry and have a stable crystal structure, ready to be made into strong straps.

Why is This a Big Deal? Three Super Benefits.

For someone looking to buy machinery (a B2B purchaser), this isn’t just about drying; it’s about making a better business. Here are the three biggest reasons why our Infrared Rotary Dryer is essential:

1. Lightning Speed & Perfect Quality

Time is money in manufacturing. Traditional dryers can take hours. Our Infrared Rotary Dryer gets the job done in only 20 minutes. More importantly, it ensures every flake is dried evenly. This uniform treatment is the secret to making PET straps with high tensile strength, consistent dimensions, and excellent stability. No weak spots, just reliable quality.

2. Huge Energy Savings = More Profit

All machines use power, but our dryer is designed to be incredibly efficient. By using targeted infrared energy, it saves over 60% in energy costs compared to old-fashioned drying systems. This massive saving goes straight to your bottom line, making your production much more cost-effective and environmentally friendly.

3. Ultimate Dryness for Superior Straps

The final moisture level in the plastic is critical. Even a little leftover moisture can cause problems when making the strap, weakening it. Our Infrared Rotary Dryer is so effective that it can reduce moisture to less than 100ppm (parts per million), and can even achieve levels as low as 30ppm. This ultra-dry condition protects the vital viscosity of the PET, which is the key to ensuring your final PET packing straps are strong, durable, and of the highest quality.

The Complete Package: Infrared Dryer + Strap Line

Using our Infrared Rotary Dryer as the first step in your PET packing strap “One-into-Two” production line sets you up for success. The “one-into-two” means one extrusion line can produce two straps at once, doubling efficiency! By starting with perfectly dried and crystallized flakes, every machine that follows—the extruder, the cooler, the stretcher—works better. You get:

⦁ Higher production output.

⦁ Less waste and fewer defective straps.

⦁ A final product that customers trust because of its strength and consistency.

Built on Experience and Innovation

LIANDA MACHINERY isn’t new to this. With over 2,680 machines installed worldwide since 1998, we know what global customers need. Our expertise in the Infrared Rotary Dryer technology started with importing German patents in 2008, and we have since developed our own advanced patents. We hold ISO9001 and CE certificates, guaranteeing professional manufacturing and precision.

For any business aiming to produce top-tier PET packing straps, the choice of dryer is the most critical decision. It’s the foundation of quality and efficiency.
