Dual Breakthroughs in Production Efficiency and Cost Control
Form-Fill-Seal Integrated High-Efficiency Process
This system combines forming, filling, and sealing into a single machine. FFS Shaped Bags can produce 60-120 bags per minute-far faster than conventional bag-making and filling equipment, which only manages 30-50 bags per minute. This makes it ideal for high-speed production lines handling fast-moving consumer goods like potato chips and nuts.
Material utilization is improved by 15%-20%. Special-shaped bags reduce edge waste through structural optimizations, such as side gusset folds. For a 1000ml liquid package, the cost per bag is 0.1-0.3 yuan lower than traditional pre-made bags.
Low Energy Consumption and Equipment Compatibility
There's no need for pre-made bag storage. FFS equipment makes bags directly from roll film, saving 80% of storage space. This also cuts logistics costs by 30% compared to transporting pre-made bags.
The system easily handles quick switches between multiple specifications. By replacing forming molds-with a changeover time of ≤15 minutes-the same equipment can produce special-shaped structures like three-side sealed bags, stand-up pouches, and handle bags. This suits brands with multiple SKUs that need to switch production quickly.
Scenario Adaptability of Functional Design
Stand-up zipper bags offer two key benefits: they stand upright for easy display and can be sealed repeatedly. The zipper's strength is ≥10N/30mm, and the bags stand at an angle of ≥85°. For products like pet food, this design extends the freshness period by 50% after opening, making them ideal for snacks and detergents.
Three-side sealed special-shaped bags-such as heart or star shapes-provide visual differentiation and precise volume control. The bag dimensions have an error margin of ≤±1mm, and volume accuracy is ±2%. These eye-catching designs appeal to the holiday gift market, like Valentine's Day chocolate packaging, and are used for candies and gifts.
Handle special-shaped bags combine portability with load-bearing capacity and anti-theft features. The handle can withstand a pull force of ≥30N, and the anti-theft tear strip requires 15-20N of force to open. They're suitable for packaging 5-10kg of rice, with handles passing a fatigue test of 100 uses without breaking, making them ideal for cooking oils, grains, and daily necessities.
Spouted special-shaped bags allow easy access to liquids or pastes while preventing leaks. The spout's sealing strength is ≥25N, and it passes a pressure test-remaining leak-free under 100kPa for 30 minutes. These are perfect for jams, shampoos, cosmetics, and condiments.
Technical Upgrades in Packaging Performance
Enhanced Protection with Multi-Layer Barrier Structures
A typical structure consists of PET (12μm) + EVOH (7μm) + PE (80μm). This combination achieves an oxygen transmission rate of ≤5cm³/(m²・24h) and a water vapor transmission rate of ≤1g/(m²・24h). It's ideal for foods that need long-term freshness, such as coffee and milk powder.
For anti-puncture design, a metallocene PE (mPE) inner layer is added, increasing puncture strength by 40%. This prevents sharp particles like nuts and beans from piercing the bag.
Anti-Static and Explosion-Proof Treatments
For chemical raw material packaging, the bags include conductive carbon black, resulting in a surface resistance of ≤10⁸Ω. When paired with the FFS equipment's static grounding system, they meet explosion-proof requirements for flammable powders like carbon powder and aluminum powder, complying with ATEX Zone 21 standards.
Differentiated Value in Marketing and User Experience
Shelf Display Advantages of Special-Shaped Structures
Special-shaped bags-such as hexagonal or cylindrical designs-increase supermarket shelf visibility by 20%. According to Nielsen's 2024 FMCG packaging survey, these shapes extend consumer visual attention by 1.5 seconds and boost conversion rates by 12%.
Customizable window designs-like a transparent PET window covering 30% of the bag-let consumers see the product directly, reducing doubts. This works well for dried goods and frozen foods.
Ergonomics and Usability
Arc-shaped bag bodies increase grip friction by 30% (with a surface roughness of Ra=1.6μm), making them easy for the elderly and children to hold. For laundry detergent packaging, a slanted spout design reduces residual product to ≤5%, compared to 15% in traditional bags.
Innovations in Environmental Protection and Sustainability
Single-Material and Reduced-Weight Designs
Pure PE special-shaped bags-such as LDPE+LLDPE composites-have a 92% recycling rate. This reduces recycling difficulty by 25% compared to traditional PET/PE composite bags. Thickness is reduced from 100μm to 80μm, cutting material consumption by 20%.
Adaptation to Degradable Materials
Using PBAT+PLA blended films-with a degradation rate of ≥90% within 180 days-FFS equipment can produce stand-up special-shaped bags. These are suitable for packaging fresh fruits and vegetables, complying with GB/T 38082-2019 standards.
Industry Applications and Selection Recommendations
In the food industry, priority should be given to stand-up zipper special-shaped bags, which offer both freshness retention and display benefits. Matte printing-with a haze of ≥85%-enhances a premium feel, making them ideal for nut gift boxes.
For the daily chemical industry, spouted special-shaped bags paired with three-dimensional labels (in-mold labeling, IML) and tamper-evident designs-with tear strips requiring 18-22N to break-work well for shampoos and body washes.
In the chemical industry, anti-static special-shaped bulk bags (with a capacity of 500-1000kg) feature valves that discharge at a rate of ≥100kg/min, making them suitable for automated feeding of powder raw materials.
