The five that matter most

Heel (the concentrated residue left after draining), ghosting (permanent pigment shadow in the bottle wall), prior-contents declaration (the document the whole trade depends on), rebottling (new bottle, reused cage) and specific gravity (the number that decides whether your equipment can lift it). Understand those five and most of this trade makes sense.

B

Backlighting
Holding a bright light against one wall of a bottle and viewing through from the other side. The fastest way to find haze, film and ghosting that are invisible from the lid opening. → Buying checklist
Bottle
The plastic inner receptacle of a composite IBC — usually blow-moulded natural HDPE, 60 to 80 mil wall. The consumable part of the container.
Buttress thread
The asymmetric coarse thread used on most IBC outlets and lids. S60x6 is the common North American outlet designation. → Valve sizes
Backhaul
A return leg a truck would otherwise run empty. When your load fits one, the marginal cost is small and we price it accordingly — usually in exchange for a two or three day window. → Transport
Brix
A measure of dissolved sugar by weight percent. A 70 Brix juice concentrate is about 70% sugar and has a specific gravity near 1.35, which makes a filled 275-gallon tote roughly 3,120 lb.
Bulkhead fitting
A through-wall fitting with gaskets either side, used on upcycled builds. The correct way to add a port to a bottle; a self-tapping fitting will not hold reliably under head pressure.
Butterfly valve
A quarter-turn valve where a disc rotates within the bore and the seat does the sealing. Cheap, compact and the default on composite IBCs.

C

Cage
The welded galvanised steel tube frame around a composite IBC's bottle. Structural, repairable, and typically outlives three or four bottles.
Camlock
A quick-connect coupling system pairing a male adapter with a female coupler, lettered A to F by end connection. Type F on a tote valve and Type C on the hose is the usual pairing.
CIP — clean in place
Cleaning a vessel without dismantling it, using a spray device and circulated chemistry. On our line it means caustic at 2–4%, 160–180°F, through a 360° rotating lance. → The reconditioning line
Composite IBC
An IBC with a rigid plastic inner receptacle in a separate structural outer frame — the standard caged tote. UN design type 31HA1 for liquids.
Compression set
The permanent flattening a gasket takes on after long compression. A compression-set seal will weep even though it looks intact; replace it routinely.
Crazing
A network of fine surface cracks in a polymer, usually from chemical attack or stress. In a bottle wall it is the beginning of failure.
Cage-only
A sound galvanised frame sold without a bottle, at roughly 5–10% of new-unit cost. The input to rebottling, and cheap raw material for racking and fabrication.
Camlock
A quick-connect coupling system pairing a male adapter with a female coupler, lettered A to F by end connection, plus DC and DP caps and plugs. → Valves & fittings

D

DAF — dissolved air flotation
A water treatment stage where micro-bubbles lift fine suspended solids and oils to a skimmed surface layer. The stage that makes wash-water reuse viable rather than theoretical.
Diversion certificate
A document stating unit counts, weights by material stream, destination routes and dates for an end-of-life batch. What auditors ask for when they want evidence rather than assurance. → Recycling & regrind
Dust cap
A plastic cover over the outlet valve, usually tamper-evident. Both transit protection and visible proof nobody has opened the valve since loading.
DAF
Dissolved air flotation. The wash-water stage where micro-bubbles lift fine suspended solids and oils to a skimmed surface layer — what makes recirculation viable rather than theoretical.
Diversion rate
The share of inbound material, by weight, that leaves by a recovery route rather than to landfill. Ours was 97.4% in 2025, measured against certified gate weights. → Loop Ledger

E

Exchange
Delivering clean graded units and collecting dirty ones on the same truck. Freight is paid once instead of twice and nobody waits for a wash cycle.

F

Food-grade
Not a certificate. A status requiring compliant contact materials, documented edible prior service, segregated handling with recorded cleaning, and the records to prove all three. → Food-grade vs industrial
Frame gauge
A jig used to check whether a cage is square. Diagonal measurements across the top frame differing by more than about half an inch mean the cage is a reject.
First-use
A container that has held exactly one product, once. The best value in the catalogue when we can get it — visually indistinguishable from new at close to Grade A prices. → New & first-use

G

Ghosting
A permanent shadow left in a bottle wall by a prior pigment, resin or dye that has migrated into the polymer. It cannot be washed out and it caps the achievable grade.
GMA pallet footprint
The 48 × 40 inch North American grocery pallet footprint, which almost all composite IBCs to 350 gallons share. The reason they fit standard racking, dock plates and trailers.
Grade A / B / C
Our contractual condition definitions. A: food-grade eligible or rebottled. B: washed industrial. C: rinsed, as-is, non-contact. → Reconditioned totes
Gross mass
Container plus contents. Stated on the UN marking as a maximum; exceeding it voids the packaging authorisation.
GMA footprint
The 48 × 40 inch North American grocery pallet footprint that almost all composite IBCs to 350 gallons share. The reason they fit standard racking, dock plates and trailers.

H

HDPE
High-density polyethylene. The polymer almost all IBC bottles are made from — excellent with water, acids, alkalis, salts, glycols and surfactants; poor with aromatics, chlorinated solvents, fuels and heat.
Heel
The last gallon or two of product left in the bottom radius after draining. The most concentrated part of the residue, and the part that belongs in a drum rather than in your rinse water.
Hydrostatic test
A pressure test using liquid. We run it on 100% of food-line units and on a sampled basis for industrial grades.
Head pressure
The pressure exerted by a column of liquid — about 0.43 psi per foot. A three-foot stand gives roughly 1.3 psi at the outlet, which runs a soaker hose and not a sprinkler.
Heel tank
One of four segregated tanks at the pre-drain station, by prior-product family: aqueous neutral, caustic-compatible, oil and fat, and quarantine. Mixing them is the mistake that shuts a line down.

I

IBC
Intermediate bulk container — intermediate in size between a drum and a tanker. In North American trade usage, 'tote'.
ISPM-15
The international standard requiring heat treatment and marking of solid wood packaging in international trade. Applies to timber IBC pallets; steel and composite bases fall outside it. → Pallet types

J

Jig
The press fixture used to bring a racked cage back towards square, against a frame gauge. Not a hammer — forcing a badly racked frame overstresses the weld nodes.

L

Leakproofness test
An air pressure test with a soap-film or pressure-decay check. Required at least every five years for IBCs in hazardous materials service under 49 CFR 180.352.
Loop score
Our own estimate of how many further service lives remain in a container. A composite bottle has roughly seven honest lives in total; the cage has three or four bottles in it. → Tote Studio
Load centre
The horizontal distance from a forklift's fork face to the load's centre of mass. Capacity plates state a figure at 24 inches; a 48-inch-deep tote sits well beyond that and capacity falls away quickly.
Loop Ledger
Our published environmental arithmetic, including the method, the emission factors and the parts we cannot measure well. → Loop Ledger

M

Mil
One thousandth of an inch. IBC bottle walls run roughly 60 to 100 mil depending on format and specification.

N

N11 code
Three-digit service numbers like 411 and 911. Area codes and exchange codes of this pattern are invalid in the North American numbering plan, which is one of the checks our request form applies to a phone number.
Nominal capacity
The marketed volume — 275 gallons, 330 gallons. Usable capacity is roughly 3–4% lower because of required headspace and outlet position. → Size chart
N11
Three-digit service codes such as 411 and 911. Area codes and exchange codes of this pattern are invalid in the North American numbering plan — one of the checks our request form applies.

P

Packing group
The degree of danger of a hazardous material: PG I high, II medium, III low. The UN marking letter X covers I, II and III; Y covers II and III; Z covers III only.
Passivation
Chemical treatment that restores the chromium oxide layer on stainless steel after mechanical work. Part of refurbishing a stainless IBC.
Periodic inspection
The 2.5-year external visual inspection and 5-year full inspection and leakproofness test required for IBCs in hazmat service, with records. → Hazmat shipping
Prior-contents declaration
A signed statement from the site that generated a container, naming the last product and confirming empty-to-drain status. The document everything else in reconditioning depends on.
Packing group
The degree of danger of a hazardous material: PG I high, II medium, III low. The marking letter X covers I, II and III; Y covers II and III; Z covers III only.
Programme (wash)
One of five routes a container takes through our line: P1 ambient rinse, P2 hot detergent, P3 caustic clean-in-place, PF the food line, or refused. → Reconditioning

R

RCRA empty
The regulatory condition at which a container holding hazardous waste residue is treated as empty under 40 CFR 261.7 — broadly, all waste removed by common practices and residue below prescribed thresholds. Acutely hazardous residues require triple-rinsing.
Rebottling
Fitting a new blow-moulded bottle into a reclaimed, straightened cage and pallet. A virgin contact surface at roughly 55–65% of new-unit cost, keeping 100% of the steel. → Rebottled totes
Reconditioner mark
The marking a registered reconditioner applies to a restored UN packaging, carrying its code and the month and year of reconditioning, alongside the original design-type marking.
Regrind
Granulated HDPE from cut and washed bottles, sold as feedstock for non-food moulded and extruded products — drainage pipe, crates, agricultural fittings, composite lumber.
Rebottling
Fitting a new blow-moulded bottle into a reclaimed, straightened cage and pallet. A virgin contact surface at 55–65% of new-unit cost, keeping 100% of the steel. → Rebottled totes
Reconditioner mark
The marking a registered reconditioner applies to a restored UN packaging, carrying its code and the month and year of reconditioning.

S

S60x6
The common North American IBC outlet thread: a 63 mm buttress thread with a 6 mm pitch, measuring 61–63 mm across the male crests. Not interchangeable with S56x4.
Specific gravity
A liquid's density relative to water. The number that decides filled weight, and therefore which rack beams, pallet jacks and lift gates can handle your container. → Weights & footprints
Spray ball
A fixed perforated sphere that distributes wash water inside a vessel. Simpler and less effective than a rotating lance; fine for rinses, inadequate for caustic work.
Stack rating
The maximum superimposed load a filled container may carry, stated on the UN marking. In practice a two-high stack of filled composite IBCs requires a square cage, sound welds and an undamaged pallet.
Stainless 304 / 316L
The two common stainless grades for IBCs. 316L adds molybdenum for chloride and acid resistance and the low-carbon designation improves weld corrosion resistance; 304 is sufficient and cheaper for solvents, alcohols and general duty.
Stress whitening
White, crazed areas at a bottle's lower corner radius caused by over-filling, freezing or impact. Where bottles fail, and they fail suddenly.
Sniff bench
The station where a washed container is backlit and smelled at the lid before a grade is confirmed. Two independent noses on anything heading for a food-grade call.

T

Tare
The empty weight of a container. About 137 lb for a 275-gallon composite on a steel pallet.
Tri-clamp
A sanitary clamp fitting used on stainless vessels, sealed with a gasket between two ferrules. Standard where cleaning must be validated.
Triple rinse
Three successive rinses with fresh liquid, draining between each. The prescribed decontamination method for certain pesticide and acutely hazardous residues, and the baseline of our own ambient programme.
Tare
The empty weight of a container — about 137 lb for a 275-gallon composite on a steel base, 124 lb on composite and 131 lb on timber.
Two-failure rule
A bottle reaches the granulator only after failing reuse twice: once at the inbound bench and once after a wash attempt. It follows from chemistry rather than from policy.

U

Ullage
The empty space left above a liquid in a filled container. Required by filling limits so the contents can expand without pressurising the vessel.
UN 31HA1
The design type code for a composite IBC for liquids with a plastic inner receptacle in a steel outer frame. The code on most caged totes you will meet. → UN marking decoder
Ullage
The empty space left above a liquid in a filled container, required by filling limits so contents can expand without pressurising the vessel.

V

Valve boss
The moulded outlet feature on the bottle. Designed to hold a valve and resist static head — not to carry a pump or a rigid pipe run. A cracked boss is unrepairable.
Viton (FKM)
A fluoroelastomer used for seals in aromatic, chlorinated, fatty, fuel and higher-temperature service, where EPDM swells and fails. → Lids & gaskets

W

Weight ticket
The certified-scale record of a load's gross weight and count. The basis of every purchase settlement and the denominator in our diversion arithmetic.
White rust
The powdery white zinc oxide bloom on galvanised steel. Cosmetic in itself; red rust through the zinc at a structural member is the reject criterion.
