USA-Made Plastic Freezer Spacers for Faster Blast Freezing

Altium’s plastic freezer spacers are manufactured in the USA from 100% recyclable materials and engineered for high-throughput blast freezing and cold storage applications. Whether you’re processing meat, poultry, seafood, or packaged foods, our spacers deliver proven airflow performance that wood separators simply can’t match. Place one between each pallet layer and cold air circulates freely in six directions — eliminating cold spots, reducing freezing times, and lowering energy costs. Both the Standard Egg Crate and heavy-duty Maxi designs meet FDA regulations for food packaging applications, are fully nestable for compact storage, and require zero maintenance.

Two designs, one purpose — engineered airflow that reduces blast freezing time by up to 25% versus wood separators.

The Standard 40″ × 48″ egg crate plastic freezer spacer delivers six-way vertical and horizontal airflow, reducing average blast freezing time by up to 17% compared to wood separators. Its egg crate surface pattern maximizes cold air contact across every product layer for consistent, uniform freezing throughout the pallet. Storage efficiency is exceptional — a 6-foot high space holds 500 Standard spacers compared to just 25 wood spacers or 36 aluminum spacers, dramatically reducing your storage footprint between uses.

The Maxi 40″ × 48″ heavy-duty plastic freezer spacer is built for the most demanding blast freezing operations. Its 2.25″ height profile delivers three times more airflow than the Standard design, reducing average blast freezing time by up to 25% and supporting pallet loads up to 3,600 lbs. The extra height drives faster cold air circulation through every layer of palletized product — ideal for high-volume meat processing, poultry, and seafood cold storage facilities. When storage space allows, the Maxi is the highest-performance option in the Altium freezer spacer lineup.

CureSlip is an optional surface treatment available on all Altium plastic freezer spacers, designed to minimize box slippage during pallet transport without affecting nestability or performance. CureSlip-treated spacers maintain their smooth surface, making them easier to clean and sanitize — an important consideration for FDA-regulated meat, poultry, and seafood processing environments. Available for both Standard and Maxi designs. Request CureSlip when placing your order.

Color identification striping is an economical way to track and manage your plastic freezer spacer inventory across facilities and shifts. Striping can be used to verify ownership, differentiate stock held by multiple customers, or track which spacers are used with specific products — helping prevent cross-contamination between poultry, beef, and seafood in shared cold storage environments. Available on Standard and Maxi designs.
