Grow Tools Mylar Bags

Grow Tools 91 x 130cm Mylar Bags provide top-tier, long-term environmental protection for large botanical harvests and sensitive organic produce. Unlike lower-grade, thin laminated polyester pouches that allow light and oxygen to degrade contents over time, these genuine Mylar bags feature an ultra-dense, reflective metallised layer that blocks out 99% of light - including non-visible wavelengths - while creating an impermeable oxygen barrier.

When storing organic produce for extended periods, exposure to ambient light and oxygen are the leading causes of aroma loss, active compound degradation, and moisture spoilage. By forming a total barrier against light, air, and external humidity, these heavy-duty Mylar pouches ensure your cured produce retains its original essential oils, colour, moisture level, and overall quality over long-term storage.

Measuring a massive 91 x 130 cm, these extra-large pouches are specifically sized for commercial yields and high-volume batch storage. The durable material is tear-resistant and puncture-proof, making it suitable for heat-sealing with standard bag sealers or household irons for an airtight, tamper-evident seal.

Pro-Tip: For maximum long-term preservation, pair these Mylar bags with appropriate oxygen absorbers or 2-way humidity packs prior to heat-sealing. Always double-check your heat seal along the rim to ensure a completely airtight, lightproof environment.

Key Benefits:

• 99% Lightproof Barrier: Blocks visible and non-visible light spectrums to prevent light degradation and preserve delicate herbal profile.

• Impermeable Oxygen & Moisture Shield: Stops oxidation and humidity fluctuation, maintaining fresh aromas, colour, and overall produce quality.

• Superior to Cheap Polyester Bags: Constructed from heavy-gauge Mylar that offers true opacity, unlike thinner, light-permeable alternatives.

• Massive Bulk Capacity: Generous 91 x 130 cm footprint is ideal for storing large crops, volume harvests, and bulk batching.

• Heat-Seal Compatible: Easily sealed using standard impulse heat sealers or household heat irons to create an airtight, secure package.

• Heavy-Duty Construction: High puncture and tear resistance guards against accidental breaches during storage and transport.
