Stretch Wrap Film Packaging and Labelling Guide for Construction Firms: the 2026 season Guide No.202

Demand for stretch wrap film in Switzerland has been growing steadily, and buyers who reserve capacity early avoid the tightest production months. This guide for Construction Firms sets out what to check, what to ask and what to document before you place an order.

Packaging and Logistics

Label every carton with the PO number, SKU, colour and quantity so that receiving is quick and accurate. Bulky items cost more to ship than to make, so agree the packing format and the flat-pack design early. Photograph the packed pallet before it leaves the factory; it settles most damage arguments before they start.

What Goes Into the Product

Cheap substitutes usually appear in the finish, the filling or the hardware, so inspect those areas first. A good stretch wrap film starts with the LLDPE cast film in 15-23 micron, so agree the material grade before you discuss price. The LLDPE cast film in 15-23 micron determines most of the look, feel and durability, and it is the first item to write into the specification. Consistency across a batch is a common weak point in stretch wrap film, so approve a range sample rather than a single piece. For stretch wrap film, the construction matters as much as the material: watch the film gauge and roll winding.

Choosing the Right Supplier

Ask the factory how many stretch wrap film lines it runs and whether your order shares a line with another buyer. Request the production schedule before you pay the deposit, so you can see where your order sits. Visit or video-audit the line; a five-minute walk-through reveals more than a page of certificates. Confirm who owns the moulds, the artwork and the tooling, especially if you intend to reorder the same design next season.

Inspection Points Buyers Should Book

Measure a full sample set against the specification sheet, and record every deviation, however small. The critical test for stretch wrap film is tensile and puncture test, and it should be run on the production batch, not on a golden sample. Agree in writing what happens if the inspection fails, including who pays for rework and re-inspection. Keep an approved golden sample sealed at the factory and a matching one in your office.

Lead Time and Order Planning

Confirm the packaging materials and the labels before production starts, since late packaging delays the whole line. Book capacity in advance for peak months; a factory that is full in August cannot rescue a late October order. Standard production for stretch wrap film runs 30 to 60 days after sample approval, so build the calendar from the approval date.

Documents and Certifications to Request

Products with a safety function carry their own documentation, so keep the certificates on file for the programme. For Switzerland, check the labelling rules on material content, care instructions and country of origin before printing. Sustainability claims must be backed by traceability, so keep certificates for recycled or responsibly sourced material. Ask for social compliance documentation such as a BSCI, Sedex or WRAP audit dated within the last twelve months.

Final Checklist

Sign, approve, inspect, pack, document. Those five verbs separate a calm season from a costly one.
