Polypropylene gaylord boxes, produce crates, meat lugs, corrugated boxes, and pallets — engineered for food-grade performance, reuse, and total cost savings.
Request a Quote from ElipackoPolypropylene has earned its position as the default material for industrial bulk and unit-load packaging — and for good reason. Whether you need a gaylord box capable of holding 1,200 lb of bulk ingredients, a stack of produce crates that can move from field to cold room to supermarket shelf without a single rupture, or meat lugs that pass repeated sanitation cycles without absorbing odors or harboring bacteria, PP containers deliver where cardboard and single-use packaging consistently fall short.
At Elipacko, we supply a full range of PP containers designed to fit within existing supply-chain infrastructure. Our containers align with standard pallet footprints, nest or stack for efficient return logistics, and are available in food-grade virgin resin formulations that meet FDA 21 CFR requirements out of the box.
PP gaylord boxes replace single-use cardboard bulk containers in applications ranging from dry-goods distribution to liquid-resistant agricultural bulk packing. Standard footprints of 40×48 in and 48×45 in match GMA pallets precisely, eliminating the overhang and edge compression failures seen with undersized cardboard gaylords. Wall thickness in the 3 to 5 mm range provides rigidity that cardboard achieves only with triple-wall construction — at a fraction of the lifespan.
A PP gaylord that completes 50 round trips replaces 50 cardboard boxes, reducing per-trip packaging cost by 60 to 80 percent depending on commodity pricing. The box does not absorb moisture, does not collapse in humid cold-storage environments, and does not shed fiber into food products — a recurring audit finding when paperboard is used in FDA-regulated facilities.
PP produce crates are the workhorse of modern fresh-produce logistics. Their open-mesh or ventilated sidewall construction promotes air circulation, a critical factor in post-harvest temperature management. They are lightweight enough that workers can carry a full stack without ergonomic risk yet rigid enough to be stacked six to eight high in a refrigerated truck without deflecting.
Unlike single-use wax cardboard boxes, PP produce crates return to the packing house for washing and reuse. A crate washed with standard food-contact sanitizers at temperatures up to 180°F is fully restored to hygienic service — no fiber degradation, no wax delaminaton, no structural weakening. In a year-round operation, a reusable PP crate fleet pays back its acquisition cost in fewer than two growing seasons for most commodities.
Meat lugs operate in one of the most demanding environments in food manufacturing: ambient temperatures near freezing, aggressive USDA-mandated sanitizing chemicals, physical abuse from high-throughput processing lines, and regulatory scrutiny that tolerates no compromise on food-contact material compliance. PP meets every one of these demands.
Food-grade PP lugs molded from virgin FDA 21 CFR–compliant resin resist lactic acid, blood, and fat without staining, swelling, or off-gassing. Their smooth internal radii eliminate crevices that harbor biofilm, a requirement for HACCP compliance. Copolymer grades maintain toughness at blast-freeze temperatures as low as –20°F, allowing the same container to move from cutting room to blast cell to frozen storage without switching containers mid-process.
Twin-wall PP corrugated boxes provide the folding, stackable format that cardboard boxes offer — combined with waterproof walls, reusability, and full color printability. They are specified in produce, seafood, and food-processing secondary packaging wherever condensation, wash-down, or repeated handling would destroy cardboard after a single use.
PP pallets round out the container system. A PP pallet in rackable or nestable configuration weighs 30 to 50 percent less than a wood pallet, does not harbor pests, requires no heat treatment for international trade compliance, and survives the same wash cycles as the containers it carries. For closed-loop supply chains, running a full PP system — pallet, gaylord, inner container — delivers the lowest total material cost per trip and the cleanest compliance profile.

Polypropylene holds a long-standing recognition under FDA 21 CFR 177.1520 for use as a food-contact material. When containers are molded from virgin, undyed PP resin, they meet the same compliance standard across the entire container family — gaylords, crates, lugs, corrugated boxes. There is no secondary testing burden, no regulatory ambiguity, and no certificate management headache that comes with multi-material assemblies.
PP does not leach plasticizers into food products under normal cold-chain or ambient distribution temperatures. It is BPA-free by composition — polypropylene has never contained bisphenol A. For food manufacturers operating under FSMA preventive control programs, PP containers support a clean materials-management record.
PP has a density of approximately 0.91 g/cm³, making it lighter than many competing rigid plastics. In bulk container applications, this translates into measurable freight savings on every truck, every lane, every year. A fleet of 1,000 PP gaylord boxes that each weigh 4 lb less than a single-use cardboard alternative saves thousands of pounds of tare weight per full truck-equivalent — weight that can be allocated to payload product instead.
The stiffness-to-weight ratio of PP is excellent, meaning thinner wall sections can achieve the same structural performance, further reducing unit weight without sacrificing compressive strength under stack loads.
PP containers encounter a wide range of substances across their service life: acids from fruits and meat, alkaline sanitizers, surfactant-based cleaners, and occasional contact with essential oils, fats, and solvents. PP's chemical resistance profile is broad — it resists most dilute acids, bases, alcohols, and aqueous solutions with minimal swelling, staining, or stress-cracking.
This resistance is not a coating or surface treatment that wears away. It is an inherent property of the polypropylene polymer. A PP gaylord on its 50th trip is chemically resistant for the same reason it was on its first trip — the bulk material properties do not change with repeated sanitation cycles.
Homopolymer PP becomes brittle below approximately 32°F, which would limit its application in frozen food logistics. Copolymer PP — ethylene-modified polypropylene — maintains toughness and impact resistance at temperatures as low as –20°F. This is the grade specified for meat lugs, frozen-produce containers, and any application where containers pass through blast-freeze tunnels or enter frozen storage.
Specifying copolymer PP for your cold-chain containers eliminates the risk of in-service cracking, a failure mode that causes product contamination events, container loss, and costly cleanups. The slight premium over homopolymer resin is recovered within the first few freeze cycles compared with the alternative of damaged containers and downgraded product.
PP carries resin identification code #5 and is accepted by industrial recyclers across the United States. At end of service life, PP containers can be granulated and reprocessed into second-generation industrial products. For companies managing extended producer responsibility obligations or sustainability scorecards, a PP container fleet provides a documented recyclability credential that single-use cardboard, wax-coated boxes, and composite-material packaging cannot match on a comparable basis.
A reusable PP container fleet is a capital investment, not a consumable expense. The per-trip cost calculation is straightforward: divide the unit acquisition cost by the number of service trips, then add per-trip washing and logistics costs. At 50 trips, the per-trip material cost of a PP gaylord is typically 70 to 85 percent lower than the cost of an equivalent single-use cardboard box — even after factoring in wash and return logistics.
Beyond direct cost, reusable PP containers reduce the labor associated with box assembly, disposal, and waste hauling. A processing facility that converts from cardboard gaylords to reusable PP gaylords typically eliminates one to two roll-off dumpster pickups per week, reduces cardboard baler maintenance intervals, and frees floor space previously occupied by flat-pack cardboard inventory. These secondary savings are real and measurable, even if they do not appear on the per-unit packaging line item.
