FKR4300 TemperatureAdjustable 16' (400 mm) Handheld Heat Crimp Sealer Key benefits Reliable, consistent seals for thick, multilayer packaging materials so products stay protected from air, moisture, and contamination. Temperature control and a wide sealing range let you match heat to material thickness for clean, strong seals every time. Integrated molded construction delivers faster, more durable sealing performance than assembled or plasticbodied sealers. Main features and specifications Model: FKR4300 temperatureadjustable heat crimp sealer. Sealing width: 10 mm (0.39'). Maximum seal length: <= 400 mm (16'). Compatible bag thickness: 8 Mil – 32 Mil. Temperature range: 0–250 C (32–482 F), adjustable to suit different materials and contents. for: Mylar, Kraft paper, aluminum foil, and other thick material bags. Not suitable for thin transparent plastic bags such as polyethylene (PE) or polypropylene. Construction: integrated molded heating element and body for improved durability and faster, more consistent sealing versus assembled or plastic machines. Handheld design for easy, convenient operation. Why customers choose the FKR4300 Prevents weak or uneven seals that cause product spoilage or leakage by allowing precise temperature and pressure control for each material and thickness. Handles thicker, multilayer packaging that standard thinfilm sealers cannot, widening the range of products you can package safely. The integrated molded design reduces heat loss and mechanical flex, producing stronger seals and longer service life. Performance and operation Adjustable heat makes it simple to set the right temperature for materials from 8 Mil to 32 Mil—reducing trialanderror and wasted bags. 10 mm sealing width provides a substantial crimp that resists separation and holds up during handling and storage. Handheld form factor gives control and flexibility when sealing bags of different sizes and orientations, including bags containing liquids. Practical applications Food packaging: Seal Mylar or aluminum foil bags for coffee, tea, dried foods, and bulk ingredients to extend shelf life and protect flavor. Retail and craft goods: Close Kraft paper or laminated bags for smallbatch products like spices, pet treats, or handmade goods where a sturdy seal matters. Liquids and samples: Create reliable seals for thickmaterial bags containing sauces, dressings, or lab samples—effective even with moist or liquid contents when used at the appropriate temperature and thickness settings. What to keep in mind Designed for thicker, opaque and multilayer materials; do not use with thin transparent PE or polypropylene bags. Match temperature and bag thickness to achieve results—start at a lower setting and increase as needed for stronger materials. The integrated molded construction improves consistency and durability versus assembled or plasticbodied alternatives. The FKR4300 offers adjustable heat control, a 16' sealing length, a 10 mm crimp width, and robust construction for dependable sealing of Mylar, Kraft paper, aluminum foil, and other thick bags. Ideal for small production runs, retail packaging, or any application that requires strong, consistent seals for thicker materials.
