Ringkasan Eksekutif
Door shrink wrapping seals a film sleeve around a door or window frame, then heat-shrinks it in a tunnel so the pack is tight and scuff-resistant. Our automatic door shrinking line takes objects about 1,000–4,000 mm long and up to 1,200 mm wide, with pack height through the tunnel listed at about 180–210 mm (confirm thinner slabs on the order), and a 4,000 mm shrink tunnel. A worked example checks a 2,100 mm door against that range and estimates tunnel time at 6 m/min.

Why doors and windows use shrink film
A bare painted door picks up dust and edge chips in storage and on the truck. A shrink sleeve holds a clean face and keeps corners from rubbing. For long doors the tunnel must be long enough that the whole pack sits inside the heat zone at once; short tunnels leave soft ends.
Layout: seal station then shrink tunnel
The frame rides on a roller conveyor. Film is drawn over the product from an overhead roll. A sealing bar closes the film on the set sides. The pack then enters the shrink tunnel, where hot air at controlled temperature tightens the film.
Conveyor speed on the seal side is about 4–9 m/min; the tunnel side is about 6 m/min. Seal power is about 4 kW; tunnel heating about 20 kW in the published specification. Power supply 380 V; air to the seal head about 6–8 kgf/cm².
Film choices are PE, PVC or POF. Heavy PE is typically 80–150 µm on this line; POF usually runs thinner (about 15–38 µm)—confirm gauge on the order. Thicker PE is available when more protection is needed.

Our light-blue door and window shrink line feeds a white rectangular frame on a green roller conveyor. Transparent film comes down from the top roll; a red sealing/heating bar presses from above to close and start the shrink. The control cabinet sits to the side with a touch screen. A second view shows a long blue tunnel with red heating elements as a framed panel rides through on rollers.

Exact sealer layout (one sealer with press devices vs multi-side seal) is confirmed on the order for your door mix.
Worked example: a 2,100 mm door
Illustrative door: length 2,100 mm, width 900 mm, thickness 200 mm.
Pengecekan kecocokan. Length 2,100 mm inside 1,000–4,000 mm; width 900 mm under 1,200 mm; height 200 mm inside 180–210 mm → class OK.
Tunnel time. At about 6 m/min, point exposure in the 4,000 mm tunnel is ≈ 4 / 6 × 60 ≈ 40 s. Total travel from leading to trailing edge for a 2,100 mm door is (4.0 + 2.1) / 6 × 60 ≈ 61 s. Seal travel at 4–9 m/min for 2,100 mm is about 14–32 s under the bar, plus index time.
Bawa pulang. Send max length and thickness together; height is often the tighter gate than length for this class.

Keselamatan dan EN 415-10
For CE markets we use EN 415-10 as the packaging-machine reference, with a risk assessment to ISO 12100. The main hazards are the hot sealing bar, the tunnel interior and the roller conveyor. Keep hands clear of the seal stroke and the tunnel mouth while the line runs.
Pertanyaan yang Sering Diajukan (FAQ) tentang Teknik
Q: Why does tunnel length matter? A: The whole door should sit inside the heat zone. A tunnel around 4,000 mm for this class supports long doors so ends do not stay soft.
Q: PE, PVC or POF? A: All three appear in the published specification. PE is common for heavy doors; POF is often chosen for clarity. Thickness typically 80–150 µm.
Q: Is this the same as a pallet shrink tunnel? A: No. This line is sized for long, flat door and panel packs on a roller conveyor with an overhead film feed and a sealing bar.
T: Standar mana yang Anda gunakan sebagai acuan untuk CE? J: EN 415-10 dengan penilaian risiko ISO 12100.
