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

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.
• 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.
• 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).

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).

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.
• 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.

For fresh produce shipping containers (especially refrigerated containers/reefers), look for industrial ethylene-control suppliers rather than consumer refrigerator absorbers. Common providers include:

• deltatrak.com — Provides Air Repair® ethylene absorbers, including blankets, mini-packets, and formats intended for ocean containers, coolers, warehouses, and produce shipments. Their larger blanket products are designed to hang in container airflow areas.
• agraconew.com — Supplies Extend-A-Life™ ethylene filters for cargo containers, reefer trucks, cold rooms, and transport applications.
• drypak.com — Offers ethylene-absorbing sachets (including zeolite-based packets) for produce boxes and transit packaging. Better suited for carton/pallet-level protection than treating an entire container.
• amelcosystems.com — Provides FreshPicks® ethylene absorber packets for produce and floral transport/storage applications.
• conservatis.com — Supplies ethylene absorbents for produce storage and transport environments.
• retarder.it — Makes ethylene absorber filters and sachets for refrigerated transport and storage.

For a shipping container, ask for:

• “reefer container ethylene filter”
• “container ethylene scrubber”
• “hanging ethylene absorber blanket”
• “pallet-level ethylene scavenger”

The right product depends heavily on:

• produce type (bananas, apples, avocados, berries, leafy greens, etc.)
• container size (20-ft vs 40-ft reefer)
• transit duration
• temperature and ventilation settings

Also check the cold chain: ethylene absorbers can slow ripening, but they will not compensate for temperature excursions, poor pre-cooling, or inadequate ventilation.

If you tell me the commodity, container size, and average transit time, I can help narrow the supplier/product type.

For cargo and shipping container applications, you need industrial-grade ethylene absorbers (often called ethylene scavengers, filters, or blankets) rather than small consumer-facing products . These industrial solutions typically use potassium permanganate-based media or natural zeolites to oxidize and neutralize the gas emitted by ripening produce.

Key industrial suppliers that cater to shipping containers, cold storage, and transit logistics include:

• QA Supplies : Offers heavy-duty container filter systems (like their SX1 Go to product viewer dialog for this item. and SX2 ethylene filters) and bulk freshness sachets designed specifically for refrigerated transport and transit storage.
• Texas Technologies : Provides cargo-shipping solutions, including large ethylene absorbing packets (in 5g, 10g, and 30g sizes) and 3 lb. to 9 lb. filters meant for bulk boxed produce in transit.
• Desiccare : Manufactures Food Life Extender® ethylene scavengers using durable, tear-resistant, FDA-compliant materials suited for direct food contact in transport.

If you share the type of produce you are shipping (e.g., tomatoes, berries, leafy greens) and the transit duration , I can help you determine whether sachets or larger mechanical filters/scrubbers would be more cost-effective for your supply chain.

To prevent fresh produce from spoiling or ripening prematurely during transit, several specialized manufacturers and industrial suppliers provide ethylene gas absorbers specifically engineered for reefer and dry shipping containers, trailers, and bulk master cartons.

The main suppliers and their container-appropriate solutions include:

• BioXTEND (Kelvin Solutions) - Manufactures BioXTEND BXT Ethylene Filters Go to product viewer dialog for this item. (such as the BXT100 Go to product viewer dialog for this item. and BXT75 Go to product viewer dialog for this item. series), which are single-use, customizable hanging filters designed specifically for refrigerated shipping containers (reefers) and trailers to eliminate ethylene gas, mold, and bacteria.

To help narrow down the best solution, tell me:

• Are you shipping via refrigerated containers (reefers) or ambient dry vans?
• What specific types of produce are in the shipment (e.g., high-ethylene producers like bananas/apples vs. sensitive items like leafy greens/berries)?

Yes. For fresh-produce reefer/container shipments, there are several commercial suppliers worth evaluating:

What I'd look at first

If you're shipping full reefer containers, I'd start with BioXTEND BXT Shield, SPMBIO AF Filters, and Texas Technologies. These are closer to the problem you're describing than consumer refrigerator products.

If you're experiencing both premature ripening and mold/decay, Bio Turbo is particularly interesting because it addresses ethylene and airborne mold/bacteria rather than merely absorbing ethylene.

One important distinction: an absorber inside individual cartons isn't necessarily sufficient for a whole 40-foot reefer. For container-level protection, ask the supplier to size the system based on commodity, load weight, container volume, expected transit duration, temperature, and estimated ethylene production.

If you tell me what produce you're shipping (e.g., avocados, bananas, berries, tomatoes), container size, and typical transit time, I can narrow this to the 3–5 most appropriate suppliers/products and compare estimated treatment capacity and cost.

Yes. For fresh-produce reefer/sea-container shipments, there are several suppliers worth evaluating:

• Stefanelli Enterprises / Ethylene Control — Particularly relevant for your use case. They offer ethylene filters designed for produce shipped in reefer trucks and sea containers, which can be mounted in the airflow system. They also make larger “blanket” filters and box-level sachets.
• Purafil — Provides ethylene-control filtration systems for transport vessels, warehouses, storage areas and other enclosed spaces. Their approach is more of an airflow/filtration system than a small packet.
• Dry Pak — Supplies 5, 10 and 20 g zeolite-based ethylene-absorbing sachets, intended primarily for placement with boxed/bulk produce during transit or storage.
• It's Fresh / RYPEN — Develops ethylene-moderating technology specifically for the post-harvest produce supply chain, including applications for growers, exporters and retailers.
• Amelco Systems / FreshPicks — Makes FreshPicks absorber packets in different sizes for produce transportation and storage.

For an actual shipping container, I'd start with Stefanelli or Purafil, rather than simply putting sachets in each carton. Container-wide airflow treatment is better suited to a reefer/sea-container environment; sachets are more appropriate when the goal is protecting individual cartons.

If you tell me what produce you're shipping (e.g., bananas, avocados, berries, leafy greens), container size, and typical transit time, I can narrow this down to the best absorber type and suppliers that can handle your shipment volume.

To prevent fresh produce from over-ripening and spoiling in transit, several industrial suppliers specialize in ethylene gas absorbers, scrubbers, and filtration systems tailored for shipping containers and reefer trucks.

The primary providers offering solutions specifically engineered for cargo transport include:
