1. Hand-Activated Foam Bags | Equipment-Free Portable Packaging

Specifications

Structure: Double-chamber laminated aluminum foil pouch pre-filled with Component A (Isocyanate) and Component B (Modified Polyether Polyol). No equipment or power required. Press the left pouch firmly to rupture the intermediate separator, then squeeze both pouches alternately by hand to blend the two liquids for foaming.Foaming performance: Initiates expansion in 3~5 seconds and fully cures within 15 seconds; fixed density at 10kg/m³; load capacity ranges from 0.5kg to 80kg, perfectly contouring irregular-shaped products for full wrapping protection.Sizes: Over a dozen standard dimensions; unit price: USD0.75~8.5 per bag. One operator can pack 50~200 pieces daily.

Application Scenarios

Sample delivery, after-sales replacement shipment, small-batch cross-border e-commerce orders, exhibition exhibits, off-grid temporary packaging. Widely used for circuit boards, ceramics, valves, small auto parts, artware and antiques.

Pros & Cons

✅ Zero capital investment, ready-to-use anytime❌ Higher unit cost for mass production, mainly for supplementary sporadic packaging

2. Semi-Automatic Foaming Machine (Model CM-811) | Workhorse for Medium-Size Manufacturers

Specifications

Power supply: 220V, 3.5KW; high-precision metering pump ensures accurate 1.1:1 mixing ratio of A & B materials with adjustable dispensing flow via handheld foam gun.Productivity: Single-operator daily consumption: 500~1000kg raw material, 2~3 times higher efficiency than hand-activated foam bags.Investment: Machine price: USD2,750~4,950; total turnkey cost (machine + initial raw material): USD3,450~6,900. Compact footprint with easy maintenance.

Application Scenarios

Factories with daily output of dozens to 300 mixed-spec orders: hardware, pump valves, auto spare parts, all-size precision instruments and medium-volume export shipments.

Pros & Cons

✅ Cost-effective, compatible with small & large items, flexible for frequent product switching❌ Manual gun operation required; unable to connect with automated production lines

3. Fully Automatic Foaming Machine (Model CM-812) | Large-Scale Assembly Line Equipment

Specifications

Configuration: PLC intelligent control system with integrated automatic film feeding, pouch cutting, precise dosing and heat sealing; one-button startup plus automatic pipeline cleaning; 220V, 3.5KW, compatible with inline production connection.Productivity: Daily raw material consumption over 1000kg, cutting labor cost by 70% vs semi-automatic equipment.Investment: Single machine price: USD8,300~17,900; full turnkey line: USD9,950~20,700, designed for stable high-volume mass production.

Application Scenarios

Large manufacturers and top cross-border e-commerce enterprises with over 200 finished goods daily: precision instruments, lighting fixtures and bulk auto parts inline packaging.

Pros & Cons

✅ High production standardization, low material waste, greatly reduced long-term labor expenditure❌ High upfront procurement cost; limited maximum package dimension by preset film width, unsuitable for oversized goods

4. Matching AB Polyurethane Raw Materials (Universal for All Machines & Bags)

Component A: Isocyanate; Component B: Modified Polyether Polyol. Water-blown eco-friendly formulation, CFC-free and low-VOC. Waste foam is recyclable for incineration with harmless disposal.Packaging: Component A: 250kg per iron drum; Component B: 213kg per iron drum for semi/fully automatic machines; pre-sealed liquid inside hand-activated foam bags. Available densities: 6kg/m³, 17kg/m³, 23kg/m³, customizable for flexible or medium-hard foam grades.

Selection Guide Based on Production Scale

Samples & sporadic shipments: Stock only hand-activated foam bags

Medium factories (50~200 pieces/day with mixed SKUs): One semi-automatic machine + backup stock of hand foam bags for urgent small orders

Large manufacturers with stable mass production (≥300 pieces/day): One full-automatic foaming line + spare semi-automatic machine + hand foam bags for random small-batch samples
