The Role of Perforated Bags in Fresh Produce Packaging

Fresh produce presents a packaging challenge: it’s alive. Even after harvesting, fruits and vegetables continue to respire, releasing moisture and gases. Packaging them in sealed plastic bags without ventilation can lead to spoilage, sweating, and mold — especially That’s where perforated poly bags come in. 

At M Plastics Inc., we manufacture custom perforated LDPE bags specifically engineered to balance moisture retention with ventilation — helping extend shelf life and reduce waste for fresh goods.

What Are Perforated Poly Bags?  

Perforated bags are low-density polyethylene bags with micro or macro perforations — small, laser-punched holes that allow controlled airflow. Depending on the size and pattern, perforations can help manage: 

🌬️ Gas exchange (oxygen in, CO₂ out) 

💧 Moisture buildup, reducing fog and condensation 

🍅 Freshness retention for delicate produce like berries, herbs, leafy greens 

We produce these bags as layflat, wicketed, or roll formats, with perforations placed during the film extrusion or conversion process.

Why Ventilation Matters 

Produce has specific respiration rates. For example: 

• Leafy greens respire quickly and need more airflow. 

• Root vegetables like carrots need minimal venting but still benefit from humidity control. 

• Fruits like tomatoes may require larger perforations to avoid condensation. 

Without venting, trapped moisture turns into condensation, which promotes rot and bacterial growth — a major problem for retail and wholesale produce sellers.
