“PE film roll” can mean a single sheet, lay-flat tubing, gusseted tubing or film that will later be converted into bags. A useful RFQ must identify the structure as well as width, single-side thickness, roll weight and core. Otherwise, two quotations may describe different products even when the headline dimensions look identical.
Specification | HengYi production range / reference | What the buyer should confirm |
|---|---|---|
Film structure | Sheet, lay-flat tubing or custom converting | How the film will run on your machine or be used at the packing station |
Width | 7 cm to 2 m | Open width or lay-flat width; include gusset if applicable |
Single-side thickness | 0.008 mm to 0.20 mm | State mm or microns per wall, not an unclear combined value |
Roll weight | 5 kg to 100 kg per roll | Maximum lifting weight and machine unwind capacity |
Paper core | Customisable | Inner diameter, core wall thickness and preferred core length |
Our normal MOQ for a custom PE film roll is 300 kg per specification. Monthly production capacity is approximately 60 tons, subject to the current production schedule and the mix of specifications.
The extrusion settings are adjusted to the confirmed film structure, width and thickness.
For lay-flat tubing, one side of the tube is one film wall. A specification of 0.04 mm single-side thickness means 40 microns per wall. If the tubing is measured as a flattened two-wall stack, the reading is approximately 0.08 mm. Always state which method is being used.
Thickness should be selected together with width, packed weight, puncture risk and downstream sealing. A very wide tube or a film used around industrial components may require a different structure from a narrow liner for lightweight goods, even when both are called LDPE film.
Width inspection confirms that the roll matches the buyer’s open-width or lay-flat-width requirement.
A heavier roll reduces changeovers, but it also increases handling weight and unwind inertia. A 5–20 kg roll may suit manual packing or frequent product changes. Larger rolls can suit continuous production when the unwind stand and lifting equipment are designed for them. We can produce rolls from 5 kg to 100 kg and customise the paper core to the buyer’s equipment.
Please provide the core inner diameter, required core length and any maximum outer diameter. A photo or drawing of the unwind shaft is useful when the machine specification is unclear.
LDPE and HDPE options are available. Film can be transparent or coloured to a Pantone reference. Semi-transparent, frosted and fully light-blocking appearances can also be specified. Anti-static, rust-prevention and degradable options are available for suitable applications; flame-retardant and conductive film are not offered.
Gravure printing is available up to 8 colours. Printed pricing excludes the plate charge, normally USD 100 per colour. Plates are stored free and can be reused for repeat orders when the dimensions, artwork and colour separation remain unchanged.
HengYi’s blown-film workshop produces custom PE film and tubing before printing or bag conversion.
Incoming resin is checked before production. During film blowing, operators monitor thickness and width. Our normal thickness tolerance target is ±3%. When film is converted into bags, dimensions are normally controlled to ±1 mm, followed by seal checks and outgoing sampling.
Finished film rolls are wrapped with bubble film for shipment. Export terms can be EXW, FOB or DDP, and payment is accepted by T/T, either in full or 30% deposit with the remaining 70% paid before shipment.
