Royal Pack Industries

Royal pack make Hand sealers are manual devices used to create airtight seals on plastic bags and thermoplastic materials, typically available in impulse (instant heat) or hot bar (constant heat) versions. Common specifications include sealing lengths ranging from 8 to 24 inches and power consumption between 100W and 1600W, depending on the size and duty requirements. 

Technical Performance Specifications

Standard technical specifications for hand sealers vary by model size and intended application: 

·         Sealing Length: Most manual impulse sealers come in standard lengths of 8 inches (200mm), 12 inches (300mm), and 16 inches (400mm), though industrial versions can reach up to 40 inches.

·         Sealing Width: Standard seals are typically 1.5mm to 3mm wide for impulse models, while heavy-duty hot bar models can produce wider seals of 10mm to 15mm.

·         Heating Time: Most impulse sealers feature an adjustable timer with settings ranging from 0.2 to 2 seconds to accommodate different plastic thicknesses.

·         Power Supply: Most units operate on standard 220V–240V AC at 50/60Hz.

·         Material Capacity: Designed for sealing a variety of films including LDPE, HDPE, PP, PVC, and laminated foil bags. Some models can seal materials up to 0.8mm thick. 

Key Features and Construction

Royal pack often prioritize durability and ease of use in their designs: 

·         Impulse Technology: Uses a brief burst of electricity to heat the element only when the handle is pressed, requiring no warm-up time and improving energy efficiency.

·         Build Materials: Durable bodies are typically constructed from mild steel (powder-coated), aluminum, or high-strength ABS plastic.

·         Transformer Types: Heavy-duty models often use copper transformers for longer life and consistent performance during continuous use, while aluminum transformers are common in lighter, more economical models.

·         Indicators: Most units include audio or visual (LED) indicators to signal when the sealing cycle is complete.

·         Cutting Option: Some models include a built-in sliding cutter or round element to seal and trim excess plastic in one step
