Answer: Yes — for baling PET drink bottles, a door-type baler is generally better.

PET drink bottles are lightweight, bulky, and very springy. If the compression chamber is open, the bottles tend to expand back and can spill out during compression. A door-type baler helps keep the material securely inside the chamber, allowing stronger compression, multiple compression cycles, and denser bales. It also makes loading, bale tying, and bale ejection easier and safer.

For different capacities:

· Small volume / limited space: a vertical door-type baler is suitable.

· Medium to large volume / professional recycling: a horizontal door-type baler is better, especially with pre-compression, bottle piercing, conveyor feeding, and automatic wire tying.

· Best overall for PET drink bottles: a horizontal door-type PET bottle baler with high compression force and automatic tying.

So, the door-type baler is the better choice for PET drink bottles because it improves bale density, reduces springback, lowers labor, and produces more stable bales for storage and transport.
