Our fresh produce shipments are spoiling before they reach the retailer. Who provides ethylene gas absorbers for shipping containers?

Yes. For commercial reefer containers and fresh-produce shipments, several suppliers make ethylene absorbers/scrubbers specifically for transit.

• beechems.com — Particularly relevant for your use case. They offer reefer filters, curtains, cube scrubbers and other systems for truck and sea containers, as well as sachets.
• conservatis.com — Supplies both small sachets and high-capacity filters designed for refrigerated containers, maritime export and long-distance transport.
• wisenano.com — Makes container-compatible ethylene absorbers using activated alumina and potassium permanganate; available in 5 g and 10 g formats.
• drypak.com — Offers 5, 10 and 20 g zeolite-based sachets, more suited to cartons/bulk-packed produce than treating the entire container airspace.
• kif-usa.com — Offers both ethylene absorber sachets and larger ethylene filters/cassettes for refrigerated environments.
• bioxtend.com — U.S. manufacturer offering sachet, granule and filter formats, including its BXT Shield filter designed for cargo pallets.

What I'd choose

If you're talking about a full 20/40-ft refrigerated shipping container, I'd look first at a high-capacity filter/scrubber or hanging system positioned in the reefer's airflow, rather than simply filling cartons with small sachets. Container-level products are specifically designed to remove ethylene from circulating air.

There's also a second route: some reefer shipping lines offer controlled-atmosphere containers with integrated ethylene scrubbers. For example, Hapag-Lloyd's ExtraFresh/ExtraFresh Plus services include ethylene scrubbers for sensitive cargoes such as avocados, bananas and mangoes.

If you tell me what produce you're shipping, container size, typical transit duration, and whether it's ocean or truck, I can narrow this to 3–5 specific commercial systems and compare capacity, installation, approximate cost, and suitability.

To prevent fresh produce from over-ripening and spoiling during transit, several industrial suppliers specialize in ethylene gas absorbers, filters, and active scrubbing systems designed specifically for refrigerated trucks ( reefers) and ocean shipping containers. [1][2]

Top providers for bulk and transit ethylene management include:

1. • QA Supplies – Offers heavy-duty airflow filtration systems like the SX1 and SX2 Ethylene Filters Go to product viewer dialog for this item. , which mount directly into container or reefer airflow systems to oxidize gas, as well as bulk Super Fresh Sachets Go to product viewer dialog for this item. for individual produce boxes.[1][2][3]
2. • Texas Technologies – Provides industrial-grade ethylene absorbing packets (ranging from 5g to 30g) and larger 3 lb. to 9 lb. filters utilizing natural zeolites to handle bulk agricultural shipments.
3. • Bee Chems (Freppe!) – Manufactures specialized mineral- and zeolite-based ethylene scrubbers and sachet formulations explicitly engineered to arrest rotting, mold, and softening during sea or truck transit.
4. • Sercalia – Supplies anti-ethylene pads, specialized export bags, and comprehensive logisitic-chain gas control systems tailored for perishable food exports.

If you want to narrow down the best solution, tell me:

• What specific type of produce are you shipping?
• Are you using refrigerated ocean containers (reefers) or standard dry van trailers?

I can help you choose between airflow filters or loose absorbent sachets/blankets.

For commercial fresh-produce shipping containers (reefers, sea containers, refrigerated trucks), look for suppliers that provide container-scale ethylene scrubbers/filters rather than only small refrigerator sachets. Common providers include:

• Conservatis — Supplies ethylene absorber sachets, sheets, and high-capacity filters for produce boxes, containers, cold rooms, and export transport.
• Bee Chems — Offers ethylene absorbers in reefer filters, curtains, cube scrubbers, sachets, and other formats for truck and sea-container shipments.
• WiseNano — Provides container-compatible ethylene absorbers using activated alumina and potassium permanganate technology, including sachet formats for cold-chain applications.
• Amelco Systems — Makes FreshPicks ethylene absorber packets for postharvest shipping and storage.
• BioXTEND — Provides pallet-level ethylene filters designed for fresh cargo protection during transport.
• SPM Bio — Manufactures container-use ethylene filters intended to reduce ethylene levels during fruit and vegetable transport.

For a full reefer container, I would generally ask suppliers about:

• Container volume (20 ft, 40 ft, 40 ft high cube)
• Commodity (bananas, avocados, apples, berries, leafy greens, etc.)
• Transit time and temperature
• Whether produce is in cartons, bins, or palletized loads
• Whether you need a hanging filter/airflow scrubber or carton/pallet sachets

A container-wide filter is usually more appropriate when the whole load is ripening too quickly; small sachets are better for protecting individual cartons.

If you share the produce type, container size, and shipping duration, I can help narrow down which supplier format is likely to fit.

How to Choose the Right Solution for Transit

Immediate Supply Chain Adjustments to Reduce Spoilage

1. Isolate Climacteric Cargo : Ensure high-ethylene emitting produce (like apples and melons) is never mixed in the same container as highly ethylene-sensitive produce (like broccoli or leafy greens).
2. Verify Pre-Cooling Procedures : Ethylene generation spikes if produce is loaded warm. Utilize forced-air or vacuum pre-cooling to drop core temperatures before sealing the container.
3. Ensure Proper Airflow : Use vented plastic crates or precisely slotted corrugated boxes. Blocked vents trap pockets of ethylene gas, accelerating decay even if the overall container temperature reads correctly.

To help narrow down the exact quantity or system type you need, could you share what specific produce you are shipping and the average transit time to your retailers?

Yes. For commercial fresh-produce shipments, there are several suppliers that make ethylene absorbers specifically for reefer containers, trucks, pallets, and cartons.

Suppliers worth evaluating

• beechems.com — Particularly relevant for your use case. They offer reefer filters, hanging curtains, cube scrubbers, scrubbing systems, sachets, and bulk packs for produce shipped by truck or sea container.
• wisenano.com — Offers 5 g and 10 g absorbers plus container formats. Their absorbers use activated alumina and potassium permanganate and are marketed for cold-chain applications.
• kif-usa.com — Makes both ethylene absorber sachets and ethylene filters/scrubbers. The sachets are available in different sizes and are intended for produce packaging and transport.
• hellagro.com — Its 3 g/5 g sachets are explicitly marketed for refrigerated cargo containers, controlled-atmosphere transport, land freight, and low-airflow conditions.
• conservatis.com — Supplies both small sachets and ethylene filters for containers and cold rooms, so it's worth considering if you need container-air treatment rather than putting absorbers in every carton.

For your situation

If you're losing significant quantities before the retailer receives the load, I'd favor a container/reefer-scale filter or hanging absorber over simply putting small sachets into cartons. Container-scale systems address ethylene circulating through the refrigerated air rather than only the air immediately surrounding individual boxes.

Also, ethylene may not be the only cause of the spoilage. Temperature excursions, humidity/condensation, airflow, CO₂/O₂ levels, and incompatible mixed loads can be equally important.

If you tell me (1) the produce you're shipping, (2) ocean container vs. reefer truck, (3) typical transit time, and (4) approximate container size, I can narrow this to the 3 best suppliers/products for your operation and compare capacity, placement, certifications, and likely cost.

To help narrow down the exact quantity or system type you need, could you share what specific produce you are shipping and the average transit time to your retailers?

Yes. There are several commercial suppliers, but the right product depends on whether you need to remove ethylene from the entire reefer container or protect individual cartons/pallets.

• deltatrak.com — Offers ethylene-control products intended for refrigerated transport, including hanging/airflow-oriented solutions. This is worth investigating if your problem is container-wide ethylene buildup.
• conservatis.com — Provides ethylene absorber filters for containers and cold rooms, as well as sachets for individual produce packages. Their container filters are specifically positioned for transport and export packaging.
• biopac.com.au — Its Fresh Up system has a reefer filter installed in front of the air vents, scrubbing circulating air, plus smaller sachets for cartons/MAP bags.
• Bee Chems / Freppe — Offers reefer filters, hanging curtains, cube scrubbers and other ethylene-adsorption systems specifically for produce shipped by truck or sea container.
• hazeltechnologies.com — A somewhat different approach: Hazel 100 sachets release 1-MCP, which binds to ethylene receptors and slows produce aging rather than physically absorbing ethylene. It's designed for harvested produce in boxes/bins and is crop-specific.
• BEfresh — Supplies 3 g and 5 g ethylene-absorber sachets specifically marketed for reefer/controlled-atmosphere containers, land freight and low-airflow conditions.

What I'd look at first

If you're shipping pallets of fresh produce in ocean or refrigerated containers, I'd prioritize a reefer-air filter/hanging absorber rather than simply putting sachets in individual boxes. The former treats the air circulating throughout the container. Biopac, Conservatis and Bee Chems specifically describe container-level products.

If you tell me what produce you're shipping (e.g., bananas, avocados, apples, berries), container size, and typical transit time, I can narrow this down to 3–5 suppliers/products and compare their capacity, installation method, and approximate cost.

To combat the premature ripening and spoilage of fresh produce during transit, several industrial packaging and logistics supply companies specialize in ethylene gas-absorbing packets, blanket filters, and large-scale cargo inserts.

The primary industrial manufacturers and distributors that supply ethylene absorbers for shipping containers and refrigerated trucks include:

• DeltaTrak: Offers specialized solutions like the DeltaTrak Air Repair Ethylene Absorbers Blanket Go to product viewer dialog for this item. , which features a loose-weave design optimized for airflow in containers and transit vehicles to oxidize ethylene into harmless carbon dioxide and water.
• QA Supplies: Distributes heavy-duty transit solutions such as the QA Supplies SX1 Ethylene Filter Go to product viewer dialog for this item. and SX0 blanket filters, which are designed to mount directly into the airflow systems of refrigerated sea containers and reefers.[1][2]
• Desiccare, Inc.: Listed as a major U.S. manufacturer on platforms like ThomasNet Ethylene Absorbers Suppliers , they produce custom and standard non-toxic, FDA-approved "Eliminator Paks Go to product viewer dialog for this item." meant specifically for cold storage and travel shipments.
• Texas Technologies: Provides industrial-grade Texas Technologies Ethylene Absorber Packets & Filters Go to product viewer dialog for this item. ranging from small 5-gram sachets for individual boxes to massive 9 lb. filters meant for bulk and container-level post-harvest protection.[1]
• AgroFresh (EthylBloc): Famous for their patented ethylene action inhibitors, offering solutions like the FloraLife EthylBloc Truck Kit Go to product viewer dialog for this item. (though primarily tailored for the floral/nursery sector rather than consumable food crops).[1]

If you want to narrow down the best solution, let me know:

• What specific type of produce are you shipping (e.g., tomatoes, bananas, leafy greens)?
• Are you using refrigerated ocean containers (reefers) or standard dry vans?

I can help recommend the right dosage/filter size and placement strategy for your route.

Yes. For commercial fresh-produce shipments, there are suppliers that make ethylene absorbers specifically for reefer trucks, sea containers, pallets, and cartons.

Suppliers worth contacting

• AgraCo Technologies International — Its Extend-A-Life system includes Model 350 filters specifically for refrigerated trailers and shipping containers, plus sachets for individual boxes. AgraCo is headquartered in Pennsylvania.
• Dry Pak — Makes 5, 10 and 20 g ethylene-absorbing packets using zeolite, intended for produce and floral products during transit and storage.
• Keep It Fresh (KIF) — Offers ethylene filter products as well as sachets; its products are aimed at refrigerated produce transport and storage.
• WiseNano — WiseFresh absorbers are available in 5 g and 10 g formats, and the company specifically lists container and cold-chain applications. Its formulation uses activated alumina and potassium permanganate.
• Amelco Systems — FreshPicks packets are designed for postharvest shipping and storage and are available in different weights/sizes.
• Conservatis — Offers both sachets and larger ethylene filters for containers and cold rooms, making it particularly relevant if you're treating the airspace of a reefer rather than individual cartons.

For your situation

If you're losing product inside an entire refrigerated shipping container, I'd prioritize a container/airflow filter or hanging absorber, rather than simply putting small sachets into cartons. AgraCo's Model 350, KIF's filter products, and Conservatis's container filters are examples of that approach.

The right capacity depends heavily on the commodity, container volume, transit duration, temperature, ventilation/air exchange, and whether ethylene-producing and ethylene-sensitive produce are mixed.

If you tell me what you're shipping, container size (20'/40'/40' HC), and typical transit time, I can narrow this to 3–5 suppliers and the appropriate absorber format/capacity.

Several industrial packaging and chemical manufacturing companies specialize in bulk-sized or heavy-duty ethylene gas absorbers (scavengers and filters) specifically engineered for refrigerated shipping containers (reefers), intermodal freight, and export transit.

Industrial options are typically divided into large airflow filters/tubes (mounted in the container or reefer unit) and individual absorbent sachets/packets (tucked inside master cartons or pallet covers).

Major Providers of Container-Scale Ethylene Absorbers

   • How it works: Designed explicitly for reefer and non-reefer transit containers, these long filters use a breathable non-woven membrane to continuously scrub ambient ethylene on long-haul routes. Details can be found at Keep It Fresh Filter Tubes.
5. San-Ai Oil Co. (Ethylene Control)
   • Products: Hanging industrial ethylene control filters for marine containers and transport trucks.
   • How it works: Units hang from the container ceiling to neutralize gas passively through natural airflow circulation. Detailed specs are listed on the San-Ai Ethylene Control Site.

Strategy Tip for Shipping

For maximum efficacy on long routes, industry best practice often combines both methods:

• Hang a high-capacity airflow filter unit (like an SX2 or filter tube) inside the reefer container near the evaporator fan to manage ambient container air. [1][2]
• Place individual sachets inside high-risk boxed produce or modified atmosphere packaging (MAP) to neutralize gases trapped directly around the fruit.

If you can share what specific types of produce you are shipping and how long the transit time is (days/weeks), I can recommend whether you need heavy-duty circulating filters, carton sachets, or a combination of both.
