What are the "hard requirements" for a projector storage bag?

Protective power: Pressure and shock resistance (hard shell /EVA hot-pressed molding), circumferential buffering, scratch-resistant lining. EVA hot pressing (compression/hot pressing molding) can produce shaped shells and inner cavity bodies, taking into account both strength and custom fit.

Durable fabric: 1680D "ballistic" grade polyester (commonly coated with PU/PVC) combines wear resistance, water repellency and deformation stability, and is a commonly used fabric for mid-to-high-end bags.

Storage and compatibility: Main compartment + partition, accessory bags for remote control, power supply, and cables; Specialized models that offer "customized cavities" for specific models such as XGIMI, NEBULA, and Samsung Freestyle have been selling well in recent years.

Portability: Dual-purpose for carrying by hand or on the shoulder, thickened handle, lightweight housing.

Ii. How to Choose? "5 Quick Choice Principles for Consumers

First, measure the dimensions: Determine the internal cavity and partition of the package based on the three dimensions of the projection body and the volume of the power adapter.

Look at the structure: For frequent business trips, choose hard-shell EVA (more stable in compression molding), and for home use or short-distance carrying, soft packaging (lighter and higher fault tolerance) is an option.

Check the fabric and workmanship: 1680D grade fabric, reinforced stitching, Bartack at key force-bearing points, and neat edge oiling/edge wrapping.

Check the zipper: Large-opening bidirectional zippers, smoothness and strength must pass industry standard tests (see below).

Look at the e-commerce reputation and the matching of the model: The brand/model dedicated packages that frequently appear on the list are often more suitable and more worry-free.

Third-party purchasing suggestions also emphasize the importance of waterproofing, shock resistance, reinforced seams and capacity planning, which can be used for cross-reference.

Iii. What equipment does a factory need to produce "high-quality and non-breakable" storage bags?

Cutting and material cutting: Automatic cutting machines /CNC cutting machines, die-cutting machines (fabric /EVA sheet materials).

EVA hot press molding line (key to hard shell/three-dimensional modeling) : Hot press (compression molding), heating table, custom molds.

Sewing equipment: flat sewing machine, edge wrapping machine, hemming machine, jujube beating machine (reinforcement of force-bearing points such as handles and shoulder straps).

Post-processing and auxiliary material equipment: riveting machine/fastener installation, forming and trimming, ironing and shaping.

Testing equipment: Zipper reciprocating fatigue/strength testing machine, tensile testing machine, wear resistance/color fastness testing, drop and vibration testing device (finished product packaging and transportation simulation). Zippers can be evaluated for strength and functionality in accordance with methods such as ASTM D2061; The ASTM/ISO system is also frequently referred to in the industry for consistency control.

Iv. Quality Requirements and Key Test Checklist

Appearance and craftsmanship: Uniform stitching, no missed or skipped stitches. The edge wrapping is smooth. The position and color difference of the LOGO/ marking are controllable.

Dimensions and fit: The fit between the main warehouse cavity and the inner liner, the effective volume of the partition and accessory bags.

Structural strength: Hand-held/shoulder strap tensile strength and jujube reinforcement. The shell is resistant to pressure and rebound (EVA hot-pressed part).

Beyond Case

Zipper/hardware: Smooth opening and closing, chain strength, pull resistance, reciprocating life - refer to ASTM D2061 and relevant industry methods.

Fabric properties: Wear-resistant, water-repellent/pressure-resistant, stain-resistant; The 1680D grade fabric and PU/PVC coating can provide better durability.

Transportation adaptability: Drop, vibration and stacking tests for the entire package (to avoid transportation damage).

Compliance (as per customer requirements) : REACH, RoHS, prohibited and restricted substances and odor control (if used in markets such as the European Union).

V. Standardized Production Process (Taking Hard-shell EVA Model as an Example)

Design & prototyping → Mold development → Surface/interior /EVA sheet composite → Cutting/trimming → Hot press forming (shell) → Trimming and deburring → Sewing assembly → Installation of zippers and accessories → Appearance/Size/function inspection → Packaging drop test → Shipment. The typical process sequence and key points are basically consistent with the EVA cases in the industry.

Vi. Why do ordinary Consumers Buy? What styles do they prefer?

The main motivation: carrying protection during business trips, dust-proof storage at home, portability during outdoor camping, and the "storage anxiety" of organizing wires and accessories.

Preferred style

Special hard shells for models (such as XGIMI, NEBULA, Samsung Freestyle, etc.) : They have high fit and good pressure resistance, and are high-frequency categories on e-commerce lists.

General-purpose soft packaging: With large capacity elasticity and many pockets, it is suitable for people with multiple devices and accessories.

Dual-shoulder/single-shoulder dual-purpose and built-in computer case: A "scene integration" that combines the carrying of a projector, laptop or screen.

The e-commerce bestseller list shows that both the custom-made hard shell models and the multi-pocket universal soft packaging models have traffic advantages, proving that both product lines have strong demand among different groups of people.

Vii. Market Conditions: Current Situation and Trend

On the demand side, the shipment of projectors is driven by home entertainment, camping/outdoor photography, education and light office work, which in turn boosts the demand for storage bags. Industry institutions expect the overall projector market to maintain a growth momentum of approximately 4% to 5% CAGR between 2024 and 2029 (with slight variations by region and scope), providing a stable "following" growth soil for storage bag accessories.

On the supply side, mature supply chains such as EVA hot pressing, 1680D fabric and zipper systems are abundant. OEM/ODM customization is flexible. The entry threshold is distinguished by quality control and model matching design capabilities.

On the channel side: Special packages for brand models are mostly sold along with the official machines or peripheral products. Both general-purpose and customized products have stable sales on cross-border e-commerce platforms and domestic platforms. Skus with "dedicated models and many accessory pockets" account for a relatively high proportion on the list.

Future development direction (Observed by reporters

Integration and ecologicalization: Modular storage design is carried out around "projector + battery + stand + screen" to form a "complete set of travel" product ecosystem.

Lightweight and eco-friendly materials: Reduce grammage while maintaining strength, and adopt a higher recycling ratio or water-based coating system to meet export compliance requirements.

Weather resistance and outdoor use: Higher water and dust resistance levels, upgraded anti-fouling and wear resistance, for camping and travel photography users.

Deep customization of models: Rapidly update molds and inner lining solutions in line with the rhythm of new projector products to shorten the development cycle.

Quality visualization: Digital labeling of zipper lifespan and pressure resistance, along with third-party testing endorsements, will become the key to making selling points transparent. Referring to the existing ASTM/ISO method system, the brand is expected to standardize and disclose key indicators to the public.
