AC Infinity Mylar Film Roll 4' x 100' — Reflective PET Sheeting for Grow Rooms, Double-Sided Tear-Resistant

AC Infinity Mylar Film Roll 4' x 100' is a tear-resistant, double-sided reflective PET sheet made to increase light coverage and boost grow-room lighting efficiency.

This large-format mylar film offers a practical way to amplify existing grow lights without upgrading fixtures. Cut to any size, the lightweight PET material lays flat on walls, floors, or greenhouse frames to redirect stray photons back toward plants and improve overall light distribution. It’s built to be thermostable and easy to maintain, making it suitable for repeated use in indoor horticulture setups.

How does this mylar film improve light coverage in a grow room?

The double-sided reflective surface captures and redirects light that would otherwise be lost to walls or the floor, making more of your lamp output usable for canopy penetration. By bouncing light back into the canopy, it evens out hotspots and can help maximize the effective footprint of each fixture without increasing energy draw. It’s especially helpful in narrow tents or rooms where light can be absorbed by dark surfaces.

• Double-sided PET foil boosts usable light by reflecting stray photons.
• Expands effective coverage area of each grow light.
• Helps reduce dark corners and uneven light distribution.

Is the material durable and safe for repeated use?

The roll is made from PET, a strong, tear-resistant polymer that tolerates the temperatures commonly found in grow spaces without warping. Its thermostable nature means it preserves reflectivity through typical heat cycles and is less likely to degrade from regular mounting and reconfiguration. The film is also easy to clean, allowing you to maintain light performance over time.

• Durable PET resists tears and edge wear during installation.
• Thermostable under common grow-room temperatures.
• Wipes clean to retain reflective efficiency.

How do I install and customize the 4' x 100' roll for different setups?

The sheet is lightweight and can be trimmed with scissors or a utility knife to match walls, tent liners, or bench surfaces. It adheres well using removable tape, clips, or staples depending on the mounting surface—allowing quick changes without permanent alterations. Because it’s sold as a long continuous roll, you can create seamless panels for fewer seams and better optical performance.

• Cuttable to any width or length for tailored coverage.
• Mount with tape, clips, or staples depending on surface.
• Use continuous lengths to minimize seams and light loss.

What environments and applications is this film best suited for?

Designed for indoor horticulture, the roll works well on tent walls, greenhouse interiors, nursery benches, and grow-room floors to improve light utilization. It’s also useful for temporary installations, propagation areas, and any scenario where boosting reflectivity is needed without new fixtures. Lightweight and portable, it transitions easily between seasonal projects or different rooms.

• Ideal for grow tents, greenhouses, and propagation stations.
• Fits floors, walls, ceilings, and bench linings.
• Portable for seasonal or temporary setups.

Who is this for: Growers, hobbyists, and professional cultivators who want a cost-effective way to increase usable light without replacing fixtures will find this roll valuable. It’s also a practical option for nurseries and educational facilities that need flexible, durable reflective surfaces that are simple to trim, mount, and maintain. If you need to expand light coverage, reduce dark spots, or create easy-to-clean reflective panels, this AC Infinity PET mylar film is engineered for that purpose.
