stretch hood machine manufacturers

The automatic stretch hood machine is a professional end-of-line pallet packaging equipment designed for dry mortar production lines. It is specially used for fully enclosed cold PE stretch film packaging of palletized bagged products, including dry mortar, tile adhesive, putty powder, thermal insulation mortar and waterproof mortar. Different from traditional rotary winding machines, it adopts cold stretch hood technology without heat shrinking. By utilizing the elastic retraction force of high-performance PE film, the machine completes one-piece full-surface covering and tight bundling from top to bottom for pallet loads. Fully unmanned and automatically operated, it effectively solves common industry problems such as loose wrapping, dust penetration, moisture absorption, cargo tilting and collapse during outdoor storage and long-distance transportation. The machine can be perfectly linked with automatic palletizing lines to form a fully closed intelligent packaging system, realizing standardized finished product packaging, storage and delivery for mortar factories.

• Cold Stretch Packaging, Energy-saving & No Product Damage: Adopts full cold stretching working mode without heating or thermal shrinking. It avoids high-temperature deformation, bag printing fading and package damage. With extremely low power consumption, it eliminates fire risks in dust-prone mortar workshops and meets industrial safety and environmental protection standards.
• Full Enclosed Dustproof & Waterproof Protection: Realizes 5–6 sides full coverage sealing for pallet goods. It completely isolates external dust, moisture, rain and snow, preventing mortar products from damp failure, powder pollution and quality deterioration during long-term outdoor storage and cross-regional transportation.
• Ultra-stable Tight Bundling, No Cargo Collapse: The high-elastic PE stretch film provides uniform and lasting tension. It tightly fixes layered bagged mortar products without loose wrapping, sliding or collapse. The neat and standard pallet shape greatly improves container loading rate and warehouse stacking safety.
• High Efficiency & Intelligent Unmanned Operation: Supports continuous automatic film feeding, stretching, hooding and cutting. Compatible with 24-hour continuous production. Equipped with PLC intelligent control system, it can store multiple size parameters, realize one-click switching and automatic line linkage, greatly saving manual packaging cost.
• Strong Compatibility & Flexible Customization: Adaptable to standard and non-standard pallet sizes and different stacking heights of 20kg/25kg/50kg mortar bags. The stretching tension and packaging height can be precisely adjusted to meet diversified packaging demands of multiple mortar formulas.
• Durable Industrial Structure & Low Maintenance: Heavy-duty steel frame with anti-rust treatment, dust-proof and wear-resistant electrical components. The whole machine features stable operation, low failure rate and long service life, fully adapting to harsh high-dust workshop environments of mortar production lines.

• Check the film feeding system, stretching mechanism, cutting device and safety sensors before daily startup to ensure no looseness, blockage or abnormal operation.
• Keep the pallet goods stacked neatly and flatly. Over-height, over-width or severely irregular stacking is prohibited to avoid film breaking and packaging failure.
• Prohibit hard foreign matters from contacting the stretching and cutting parts to prevent equipment damage and film scratching.
• Clean surface dust and residual film regularly, especially for sensors and control cabinets, to avoid dust accumulation causing signal failure or circuit failure in mortar dust workshops.
• Regularly lubricate transmission components and check the tightness of fasteners and film tension to ensure stable packaging effect.
• Cut off the power supply completely during equipment maintenance and debugging. It is forbidden to open the safety protective cover during running operation.
• Replace qualified special cold stretch PE film only. Mixed use of unqualified film will cause unstable stretching and poor packaging tightness.

• Fully automatic dry mortar production lines for large and medium-sized building material factories
• Mass production and standardized packaging of tile adhesive, waterproof mortar and repair mortar
• Putty powder, thermal insulation mortar and floor mortar finished product packaging workshops
• Enterprises requiring outdoor stock storage, long-distance container transportation and moisture-proof & dust-proof packaging
• Full-automatic unmanned packaging supporting projects linked with palletizing production lines

• Q1: What is the difference between stretch hood machine and traditional winding machine?
  A1: The stretch hood machine adopts full cold stretch integral hooding packaging, realizing full closed waterproof and dustproof effect. It features tighter bundling, better cargo stability and no heat damage, which is more suitable for long-term storage and long-distance transportation of mortar products than traditional winding packaging.
• Q2: Can the machine adapt to different mortar bag specifications?
  A2: Yes. The system stores multiple sets of programmable parameters, which can freely adapt to 20kg, 25kg and 50kg bagged products, and support customized pallet size and stacking height adjustment.
• Q3: Can the equipment work stably in high-dust mortar workshops?
  A3: Yes. The whole machine adopts dust-proof and closed protection design for electrical and moving parts, with strong anti-interference ability, adapting to long-term high-dust and high-load working conditions.
• Q4: Does cold stretch packaging affect the quality of mortar products?
  A4: No. The whole process requires no heating, which will not cause bag deformation, ink fading or mortar performance changes. The sealed packaging can effectively protect product quality.
• Q5: Is the equipment easy to maintain?
  A5: The machine has a modular structure with few vulnerable parts. Daily maintenance only requires regular dust cleaning and lubrication, with low operation and maintenance costs.
• Q6: Can it realize full-line automatic linkage with palletizing line?
  A6: Absolutely. It supports seamless docking with automatic palletizing lines, realizing unmanned automatic operation from palletizing to finished product packaging, improving overall factory automation level.
