Meta description: Colored stretch film explained: how pigment and opacity affect load security, light blocking and warehouse color coding, plus the specs and checks buyers should confirm.
Colored stretch film is polyethylene pallet wrap pigmented with masterbatch, so a roll carries either a light tint that still shows the load or an opaque color that hides it. Buyers specify color to identify loads by customer, route or shift, to conceal high-value goods, and to limit light exposure in storage. Color is a specification like thickness, and it changes handling rules on the wrapping line.
This guide covers how the film is made, where tint and opacity diverge, how to run a color-coding system, and the checks that prevent a container arriving in the wrong shade.

What Is Colored Stretch Film?
It is a PE stretch film made from LLDPE and LDPE resin with color masterbatch dosed at the extruder. The pigment is dispersed through the sheet, not printed on the surface.
Two properties are often confused. Tint is a low pigment loading that shifts appearance while the wrapped product stays readable. Opacity is a high loading that blocks the view of the load. A green tint and a black opaque roll are both “colored,” but they serve opposite purposes.
Color affects identification accuracy, load privacy and heat absorption. It also changes inspection: opaque film hides shifted cartons and damaged corners that clear film would reveal.
How Colored Stretch Film Is Manufactured
- Resin selection. The base blend sets stretch, puncture resistance and cling, and colored runs keep the same base as the clear grade so load performance does not shift.
- Masterbatch dosing. Color concentrate is metered into the extruder. Dosing accuracy decides batch-to-batch consistency and is the step most likely to drift on short runs.
- Additive balance. Tackifier, slip and anti-block agents are adjusted, because pigment particles can mask some additives and change how the film clings.
- Extrusion. Blown film gives a puncture-resistant sheet; cast film gives higher clarity and quieter unwind. The process follows the application, not the color.
- Thickness control and cooling. Inline gauging holds the micron target, since pigment hides thickness variation from the eye. Cooling rate affects haze on tints.
- Slitting, rewinding and inspection. Jumbo rolls are slit to width, rewound to length, compared against an approved color standard and packed for export.
Types of Colored Stretch Film
Tinted translucent film
Low pigment loading in blue, green, red or yellow. The load stays visible, so staff can still read labels and see carton condition. The usual choice for sorting by customer, route or dispatch day.
Opaque black film
High carbon-black loading hides contents completely, which suits high-value electronics and branded goods moving through third-party facilities. Black absorbs more solar heat, so it is a poor match for temperature-sensitive loads unless storage is shaded.
Opaque white and pastel film
Conceals the load without the heat gain of black. Common in retail distribution and food-adjacent logistics. These are wrapping films, not food-contact materials.
UV-stabilized and printed film
Dark films can be formulated with UV stabilizers for outdoor storage, with the service period stated in writing rather than inferred from color. Printed film identifies the shipper but cannot hide the load, and it involves tooling and longer lead time.
Tinted vs Opaque vs Printed Film
| Type | Pigment level | Load visibility | Light blocking | Best fit | Relative cost |
|---|---|---|---|---|---|
| Tinted translucent | Low | Clear | Minimal | Sorting by customer or route | Low premium |
| Opaque black | High | None | High | High-value and branded goods | Moderate premium |
| Opaque white or pastel | High | None | High | Retail and food-adjacent logistics | Moderate premium |
| UV-stabilized black | High plus stabilizer | None | High | Outdoor and long-dwell storage | Higher premium |
| Printed clear | None to low | Clear | Minimal | Brand and handling messages | Highest, tooling involved |
Choose a tint when operators must still read labels. Choose opaque film when concealment is the requirement, accepting that damaged corners will no longer be visible. Choose printing when the message matters more than the color.
Building a Workable Color-Coding System
There is no universal industry color code. Each operation defines its own, which is why the matrix has to be written down and posted at the wrapping station. Typical conventions include one color per destination region, one per customer account, one per dispatch day, and one reserved for quality holds.
- Limit the palette. Four to six colors cover most operations; every extra color adds a stock line and a substitution risk.
- Publish the matrix. Post it at each wrapper and in the warehouse system, and state which color wins when rules conflict.
- Separate by location. Store each color on its own pallet position; mixed pallets of similar rolls cause most wrong-color wrapping.
- Reserve a hold color for quarantine loads, and audit mis-shipments monthly.
Color works alongside labeling, not instead of it: film color survives a scuffed label, but it carries no data.
Applications by Industry
Export pallet wrapping
Tinted film separates loads by destination port or consignee in a consolidated container. Thickness and width follow load weight and wrapping method, as covered in this guide to stretch film thickness and width for export pallets.
Third-party logistics
One color per client account makes ownership obvious during picking and staging, which reduces cross-client mis-shipments in shared facilities.
High-value goods and construction materials
Opaque film removes the visual cue that invites pilferage in transit; pair it with tamper-evident tape rather than relying on film alone. Dark film on palletized profiles reduces UV exposure outdoors, but loads held for months need a stated stabilizer package.
Agriculture
Colored wrap distinguishes seedling batches and treatment groups. Bale wrapping is a different product: it needs a dedicated silage film with oxygen-barrier and UV requirements that pallet stretch film does not meet.
Specifications Buyers Should Confirm
- Thickness and width: micron or gauge with a stated tolerance, and mm to match the wrapper carriage or hand dispenser. Machine grades commonly sit in the 12 to 23 micron range; hand grades run thicker.
- Length or roll weight, and core inner diameter, usually 76 mm (3 in) for machine rolls and 50 mm (2 in) for hand rolls. A colored roll of the same diameter can carry fewer meters if loading changes density.
- Prestretch and elongation targets, because color should not change yield per pallet.
- Tack level and pigment loading, confirmed on the pigmented formulation rather than the clear grade, with a light-transmission value for opaque grades.
- Color reference and batch tolerance: a physical approved sample or a measured value, plus a numeric tolerance.
- Puncture and tear performance on the colored grade, and UV stabilization where outdoor exposure applies.
Requirements may vary by application, market and applicable standard.
Cost, Yield and Handling Impact
Colored film carries a premium over clear film because masterbatch is an added raw material and short color runs consume changeover time. The premium is modest on standard tints and larger on custom shades and UV-stabilized black.
Evaluate it on cost per wrapped pallet: meters consumed at your prestretch setting, price per kilogram, and the rework cost of a mis-sorted load. Two handling effects also matter: opaque film removes the visual check for shifted cartons, so inspect corners before dispatch, and colored film can affect photoelectric sensors, so confirm behavior on a trial roll.
Common Procurement Mistakes
- Ordering a color from a photograph instead of a physical sample.
- Treating a tint as if it were opaque, then finding the load is still readable.
- Buying black film for outdoor storage without confirming the stabilizer package.
- Changing color without re-checking thickness and prestretch settings on the wrapper.
- Assuming a custom shade has the same minimum quantity as a standard color.
- Accepting a batch with no stated color tolerance, then mixing two shades on one pallet.
Inspecting Color and Quality
- Color match against the approved sample under a daylight-balanced lamp, not mixed warehouse light.
- Opacity check on opaque grades by placing a printed sheet behind a stretched sample.
- Thickness measured across the web at several points against the stated tolerance.
- Roll weight and length against the purchase order, since pigment loading can shift density.
- Surface defects: gels, fisheyes, streaks and pigment agglomerates, which show as dark specks in light tints.
- Unwind and cling test at production speed, watching for noise, blocking and edge tearing.
- Batch comparison when two production lots are used on one order, plus export packing checks.
Dimensional, color, unwind and packing checks are practical pre-shipment items; tensile, puncture and haze data normally come from the supplier’s batch records.
Choosing a Colored Film Supplier
Ask how masterbatch is dosed and recorded. A supplier who can describe the dosing ratio, lot traceability and the reference sample kept per batch is controlling the variable behind most color complaints.
Then confirm the commercial terms: minimum quantity per shade, lead time for a custom match, sample availability, and what happens if a batch falls outside the agreed tolerance. Compare thickness, roll weight and prestretch performance of the colored grade against the clear grade you already run, so color does not become cover for a thinner film.
Frequently Asked Questions
Does colored film hold a pallet as well as clear film?
At tint loadings, normally yes when the base resin blend is the same. At high opacity, pigment can slightly reduce puncture resistance, so test the colored grade on your heaviest load.
Can I get a custom color match?
Often yes, subject to a minimum quantity and a matching step. Expect sample approval before bulk production, and confirm how shade tolerance is defined.
Does black film protect against UV?
Black blocks visible light but does not automatically block UV. Outdoor storage needs a film formulated with UV stabilizers, with the service period stated.
Why do two batches look slightly different?
Pigment dosing, resin lot variation and processing temperature shift shade. A written tolerance and a retained sample per batch keep the difference acceptable.
Is colored film more expensive per pallet?
Per roll, usually yes. Per pallet the gap narrows, because meters consumed are the same, and fewer mis-shipments offset the premium.
Can it run on an automatic wrapper?
Generally yes, but confirm sensor compatibility. Some photoelectric sensors read edges or reflections differently on dark and opaque grades.
