Application to purchase requirements

custom shrink sleeve labels

Translate a fill, line or shipping use into purchase requirements before a custom shrink sleeve labels request goes out. Destination, pack-out and document constraints change the RFQ. They are not marketing labels.

Contract packer applying printed shrink sleeves to mixed bottle shapes

Four duties that change the written brief

Carbonated beverage

Optical clarity and a high shrink ratio around a petaloid base usually keep the brief on PETG. Write fill volume in ml and the tunnel type. A cooler electric tunnel cannot use a steam-tunnel catalog maximum.

Dairy or juice bottle

Condensation, perforation and food-contact files attach to the named grade. Oxygen transmission rate and water vapor transmission rate belong on that film after the factory replies, not as a category average.

Household chemical jug

Handle cut-outs, recessed panels and HDPE neck finish change lay-flat width. Digital can reduce plate cost on short SKU lists. Conventional flexographic printing or gravure printing often keeps spot color steadier on long runs.

Promotional or multipack band

Shorter height, tear strip and perforation often move the brief to PVC or OPS. Restate band height in mm. Do not copy a full-body PETG shrink ratio onto a neck band.

Technical requirements that must stay on the RFQ

Packaging procurement managers, brand-owner packaging leads and print buyers should treat the rows below as purchase questions, not as performance trophies. Incoming quality reviewers can add tunnel windows and rewind specification. Centerfold overwrap film is a different construction from a sleeve and must not share one supplier line.

Condition	What to write	What usually breaks the comparison
Fill	Intended contents and whether food-contact or migration testing files apply	Asking for food-contact files on a non-food industrial jug without saying why
Line	Steam or electric tunnel, applicator type, and whether a full-body sleeve or a band is intended	Mixing PETG full-body film with a PVC promotional band on one quote line
Pack-out	Bottle count per shipper, paperboard caliper or edge crush test of the carton, and whether partitions ride with the pack	Copying a 45 μm sleeve gauge onto a heavy corrugated shipper RFQ
Destination	US state or ZIP, export if any, and which documents must travel with the rolls or cut sleeves	Treating inland ZIP and port-of-entry as the same delivery scope
Print trade-off	Color count and whether digital, flexographic printing or gravure printing is accepted	Hiding plate or cylinder cost inside a piece price on only one reply
Material trade-off	PETG or OPS for recycling reporting versus PVC for some shrink windows or band cost	Treating either side as a site slogan instead of a buyer choice

Limitation: a PETG web that finishes cleanly on a straight-wall PET bottle can wrinkle or split on a handled HDPE jug if lay-flat width and shrink ratio are copied without a line trial. Next: pin an inquiry option or send the application brief.
