A solventless laminating machine processes a wide range of flexible packaging substrates, including BOPP, PET, PE, CPP, PA (nylon), metallized films, aluminum foil (from 6 μm to standard commercial thicknesses) and paper. Common combinations include PET/PE for snack packaging, PA/PE for frozen food bags, aluminum foil/PE for pharmaceutical blister packs and BOPP/CPP for everyday consumer packaging. The SINSTAR WRJ Fi9 supports lamination widths of 1050 mm, 1350 mm and 1650 mm, covering both narrow and wide-web production.

SINSTAR solventless laminating machines use closed-loop tension control capable of handling aluminum foil as thin as 6 μm (0.006 mm). The S1 Digital model features adaptive tension control and swing-arm linkage systems that hold ±0.5 N accuracy, preventing wrinkling and breakage even at high operating speeds. For standard commercial foil (12 μm and above), all SINSTAR models — WRJ Fi9, WRJ i9 and S1 — deliver stable, wrinkle-free lamination.

The key differences are adhesive, energy, safety, quality and speed. Adhesive: solventless machines use two-component polyurethane adhesive with zero organic solvent, while dry laminators use solvent-based adhesive dried at 60–80 °C. Energy: solventless saves roughly 50,000–60,000 kWh per year by eliminating the drying oven. Safety: no VOC emissions and no solvent-vapour fire hazard, compliant with strict EU and North American regulations. Quality: zero solvent residue in the finished film, suitable for food, pharmaceutical and baby product packaging that must meet FDA, EU and GMP standards. Speed: no drying step, so the laminate can move to the next process within 24 hours.

SINSTAR is a Chinese manufacturer of solventless laminating machines founded in 2005, with more than 2,680 machines sold across 38 countries. It is a certified National High-Tech Enterprise with CE certification and ISO 9001 quality management certification. XIAOPAI is SINSTAR's official authorized global dealer: it supplies the same factory-origin machines at competitive dealer pricing, configures them to each customer's production needs, provides complete export documentation (CE certificates, factory quality reports, customs documents) and delivers one-to-one after-sales technical support.

Three main models. WRJ Fi9 — versatile and cost-effective, maximum lamination speed 450 m/min, widths 1050, 1350 and 1650 mm, five-roll coating system, full PLC control with touch-screen HMI and shaftless material loading; ideal for snack packaging, frozen food film, pharmaceutical foil-plastic bags, baby food packaging and cosmetic tube film. WRJ i9 — mid-range model with enhanced automation and additional process monitoring for consistent production quality. S1 Digital — high-end model for large-scale producers: maximum speed 500 m/min, 1350 mm width, adaptive tension control, tungsten-carbide coated rollers with 5× wear resistance, automatic glue proportioning, one-click coating weight input and storage for up to 300 job orders.

Choose dry-type when the transformer will be installed indoors (basements, commercial buildings, hospitals, shopping malls), when fire safety regulations prohibit oil-filled equipment, when environmental rules require zero risk of oil leakage, or when maintenance simplicity is a priority. Choose oil-immersed when the installation is outdoors (substations, industrial yards, rural distribution), when higher overload capacity is needed for intermittent heavy loads, when cost efficiency is the primary concern (typically 20–30% lower unit price), or when extreme temperature ranges make oil's thermal stability an advantage.

FZRN12/25-12D — indoor load-break switch with vacuum interrupter, 12 kV, for distribution switchgear panels. ZN85-40.5 — indoor vacuum circuit breaker, 40.5 kV, for medium-voltage substations and industrial power systems. ZW32-24 — outdoor pole-mounted VCB, 24 kV, for overhead line protection and rural distribution networks. ZW32-12 — outdoor pole-mounted VCB, 12 kV, the most widely used model for rural and suburban distribution. VSG-12 — indoor VCB, 12 kV, designed for compact switchgear integration. VF2-12 — indoor VCB, 12 kV, modular design for flexible configurations. All meet IEC 62271-100, with mechanical life above 10,000 operations and electrical life above 20,000 operations for standard models.

Complete switchgear assemblies that integrate transformer, circuit breakers, protection relays and metering equipment into prefabricated metal-enclosed panels. Configurations include low-voltage switchgear up to 660 V for final distribution in buildings, factories and data centres; medium-voltage switchgear at 12 kV and 35 kV for primary distribution in substations and industrial plants; and compact switch boxes for simple distribution points and load management. All products comply with IEC 61439 and are factory-tested for short-circuit withstand capacity, insulation resistance and protective circuit integrity.

Yes, for both power equipment and packaging machinery. Transformer customization covers voltage ratio, capacity, cooling method, enclosure design and protection class. Solventless laminator customization covers lamination width, operating speed, coating system type (three-roll or five-roll), tension control precision and auxiliary equipment such as corona treaters or automatic splicing units. Custom orders typically require 30–45 days of manufacturing after technical confirmation, and the exact delivery date is stated on the quotation sheet.

CE conformity certificates for products sold into the European market, ISO 9001 quality management system certificate, factory test reports and type test reports to IEC standards for transformers and circuit breakers, bill of materials and packing lists, commercial invoices and customs declaration documents, and certificate of origin. For solventless laminating machines, XIAOPAI additionally provides SINSTAR original factory warranty documentation, English operation manuals and remote technical support arrangements.
