NEU Bag – Terpene Infusion Bags for Flower (10 Pack)

What Are NEU Bags?

NEU Bags are mesh infusion sachets pre-saturated with terpenes. When placed inside an airtight container with cured flower, the terpene oil migrates passively from the bag into the flower over a period of 48 hours.

This process is called passive vapour diffusion — meaning the terpenes move from an area of high concentration (the bag) to an area of lower concentration (the flower) without any heat, pressure, or mechanical intervention. The result is a measurable increase in terpene content, with a corresponding improvement in aroma, flavour, and effect.

NEU Bags are produced using the Fresh Never Frozen® terpene process — a proprietary method that preserves the full terpene profile of fresh plants without heat processing, maintaining the integrity of the aromatic compounds through to the final product.

NEU Bags are distributed in Europe by Simply Green Trade.

Key Specifications

• Terpene increase: up to 5% — verified by independent third-party laboratory testing. An R&D study conducted by Fernway confirmed a measured increase of +4.18% total terpene content.
• Infusion time: 48 hours minimum — substantially all terpenes migrate from the bag within the first 48 hours under standard conditions.
• Coverage: 1 bag per 0.45 kg of flower — for a more intensive infusion, 2 bags per 0.45 kg can be used.
• No equipment required — the only requirement is an airtight vessel. No spray rigs, no mixing stations, no additional SOPs.
• Suitable for both fresh and aged flower — NEU Bags can be used restoratively (to recover terpene content lost during drying and storage) or additively (to enhance fresh flower above its natural terpene level).

Why Terpene Content Matters in Production

Terpenes are the aromatic compounds responsible for the aroma, flavour, and part of the effect profile of cannabis and hemp flower. As flower dries and ages, terpene content decreases — a process that is accelerated by exposure to air, heat, and light.

For production teams working with pre-rolls, packaged flower, or any finished product where sensory quality is a key selling point, terpene loss has three direct commercial consequences:

• Shortened shelf life. Flower that has lost its aroma profile is perceived as lower quality by buyers and end consumers. Products treated with NEU Bags maintain their terpene content through packaging, storage, and retail display — extending the window in which the product performs at its intended quality.
• Product waste from aged stock. Flower that has degraded beyond acceptable aroma standards is difficult to sell at full value and often discarded or heavily discounted. A terpene infusion treatment can bring aged or underperforming stock back within acceptable quality parameters, reducing write-offs and improving inventory recovery.
• Consistency across batches. Natural variation in flower means terpene content can differ significantly between harvests, suppliers, or storage conditions. NEU Bags allow production teams to standardise the terpene profile of their flower input, resulting in a more consistent finished product across batches.

Best For

Flower in need of terpene recovery: Cured hemp or cannabis flower that has been in storage, transit, or processing for an extended period and has lost aroma intensity. NEU Bags are well-suited to restoring terpene content to levels closer to fresh harvest.

Pre-roll production: Production lines working with cured flower as the primary input, where consistent and elevated aroma and flavour in the finished pre-roll is a product requirement. NEU Bags integrate into existing operations without new equipment or process changes.

Flower processors managing large-volume inventory: Operations holding significant volumes of cured flower across multiple storage cycles will find NEU Bags useful for maintaining consistent quality through the product lifecycle.

Not designed for: Adjusting moisture content. NEU Bags are a terpene infusion tool only. The starting moisture of the flower should fall within standard industry ranges before treatment begins.

Terpene Profiles — Available Variants

Each 10-pack is available in one of four terpene profiles. All profiles are produced using Terpene Belt Farms’ Fresh Never Frozen® terpenes.

How to Use NEU Bags — Step by Step

Required materials: NEU Bags (1 per 0.45 kg of flower), cured flower within standard moisture range, airtight vessel (mylar bag recommended), protective gloves.

1. Calculate the quantity needed. Use 1 NEU Bag per 0.45 kg of flower. For a more intensive terpene infusion, 2 bags per 0.45 kg can be used.
2. Prepare the vessel. An airtight container is required for the diffusion process to work efficiently. Mylar bags are recommended as they minimise headspace and maintain an ideal environment. Plastic bins can be used for larger batches, but are less effective due to increased headspace.
3. Place NEU Bags throughout the flower. Wear protective gloves when handling. Open the packaging and distribute the bags evenly throughout the flower mass so they are in contact with as much surface area as possible.
4. Seal the vessel and record the start time. Remove as much excess air from the headspace as possible before sealing. The 48-hour infusion period begins at this point.
5. Turn the flower once per day. Open the vessel, remove the bags, stir the flower thoroughly to redistribute it, return the bags, and reseal. Repeat a minimum of once and a maximum of four times per 24-hour period. Turning ensures even terpene distribution across the flower mass.
6. Complete the infusion after 48 hours minimum. Remove bags before the flower goes into use. If the flower is not yet needed, bags can be left in place — this continues to improve terpene absorption and retention without over-saturating the product.
