What Is Hot Melt Glue Stick?
A hot melt glue stick is a thermoplastic adhesive that liquefies when heated in a glue gun and solidifies upon cooling to create instant bonds. As professional manufacturers and designers with OEM/ODM capabilities, we engineer industrial-grade formulations that adhere to diverse materials including wood, plastic, metal, ceramics, and fabric. This fast-setting adhesive is ideal for product assembly, manufacturing, and commercial applications, offering B2B clients factory-direct wholesale, customizable solutions, and bulk supply chain support. It delivers strong, durable joints without mess or long curing times, providing cost-effective, high-performance bonding solutions for industrial partners.

What are the main types of hot melt glue stick？
EVA-based sticks
The most common type, made from ethylene-vinyl acetate, offering reliable adhesion for general crafting, packaging, and light-duty bonding on wood, paper, and plastics.
Polyamide sticks
High-performance nylon-based adhesives with superior heat resistance, strength, and durability for structural applications, automotive trim, and woodworking.
Low-temperature sticks
Designed to melt at 250–270°F (121–132°C), ideal for heat-sensitive materials like foam, fabric, and thin plastics without causing warping or damage.
Standard/high-temperature sticks
Require 380°F (193°C) or higher, providing stronger bonds and faster set times for industrial assembly, packaging, and construction materials.
APAO sticks
Amorphous poly-alpha-olefin based, offering excellent flexibility, moisture resistance, and adhesion to low-energy surfaces like PP and PE plastics.
Flexible/impact-resistant sticks
Formulated with rubber modifiers to maintain elasticity and withstand vibration, movement, and temperature cycling in applications requiring durability.
Colored/clear specialty sticks
Available in pigmented or transparent formulations for aesthetic applications, crafts, and product assembly where appearance matters.
High-strength structural sticks
Reinforced with additives for exceptional bond strength on metals, glass, and ceramics, often used in heavy-duty assembly and repairs.
Industrial-grade packaging sticks
Fast-setting formulations optimized for carton sealing, case erecting, and high-speed packaging lines with quick grab and minimal compression time.
What are the applications of hot melt glue stick
Crafts and DIY projects
Essential for hobbyists, enabling quick bonding of paper, fabric, wood, and plastic in scrapbooking, model making, and home décor with minimal setup.
Packaging and carton sealing
Widely used to seal cardboard boxes, secure shipping labels, and attach protective corners in high-speed packaging operations with instant tack.
Woodworking and furniture assembly
Ideal for edge banding, trim attachment, and temporary joint holding before permanent fastening, providing immediate bond strength without clamping.
Product assembly and manufacturing
Employed in various industries to bond components, mount inserts, and assemble consumer goods where rapid production cycles are critical.
Electronics manufacturing
Used for wire tacking, coil potting, and securing cable assemblies, offering a non-conductive, quick-setting solution for delicate components.
Automotive interior trim
Bonds upholstery, headliners, carpeting, and plastic trim components, providing durability and resistance to vibration and temperature fluctuations.
Textile and fabric applications
Enables temporary hems, seam sealing, appliqué attachment, and fabric-to-material bonding in apparel, upholstery, and home furnishings.
Floral and event design
Provides clean, fast adhesion for foam, silk flowers, ribbons, and decorative elements in arrangements, wreaths, and event displays.
Temporary positioning and fixturing
Serves as a reversible adhesive for holding parts during machining, welding, or assembly, allowing easy release when permanent bonding is complete.
Label attachment and bonding
Quickly adheres product labels to glass, plastic, and metal containers in high-speed labeling applications with consistent results.
Shoe and leather goods manufacturing
Bonds soles, attaches linings, and secures decorative elements in footwear, handbags, and leather accessories with flexible, durable adhesion.
FAQ
Q: What are the specifications of hot melt glue stick？
A: Usually the diameter of hot melt glue sticks is 11mm and 7mm, the rarer ones are 15mm, 1/2 inch and 5/8 inch to fit various glue gun types from mini detailers to industrial applicators. The length can be customized according to needs, and the common ones are 250mm and 300mm
Q: Which is more sticky, the yellow hot melt glue stick or the white hot melt glue stick?
A: The stickiness of hot melt glue sticks is not determined by color, but by the formulation, and the color is different because of the different types of tackifier resin used.
Q: How to choose the power of the glue gun reasonably?
A: Hot melt glue sticks with a diameter of 7mm can choose 15-40W hot melt glue gun, The most versatile range applications choose 60-150W glue gun, industrial level heavy application should choose more than 200W glue gun, the principle of choosing glue power The larger the diameter, the higher the softening point, the more frequent glue use the glue is used, and the more glue should be used, you should choose a glue gun with more power.
Q: Whether the same glue stick can be used in all situations?
A: Different use occasions need to choose different formulas of hot melt glue sticks, if the use process and the characteristics of hot melt glue sticks cannot be matched, the stickiness of hot melt glue sticks will not be exerted, or even lose stickiness.
Q: Are hot melt glue sticks toxic?
A: Hot melt adhesive sticks do not contain harmful substances, the products are green and environmentally friendly, and it is precisely because of the demand for environmental protection and efficiency that hot melt adhesives are used to replace solvent-type adhesives.
