Implementing impact absorption rates of 6%-80% through saudi-arabia composite bubble film or bubble composite kraft paper (thickness ≥ 0.03mm), suitable forsaudi-arabia electronic products, and fragile goods transportation protection13.saudi-arabia Special interwoven glass fiber process (such as fiberglass reinforcement) foam paper can enhance punct resistance, preventing sharp objects from piercing the packaging312 Waterproof and moisture-proof, PE coating composite process (coating thickness ≥ 0.02mm enables the paper to have IPX4 grade waterproof performance, moisture permeability ≤ 5g/(m²·24h), suitable for high humidity environment61, saudi-arabia aluminum foil composite structure (such as PET/AL/CPP) further blocks water vapor and oxygen.
Using biodegradable k paper base material (basis weight 70-150g), in compliance with environmental standard 28018, bubble composite kraft paper supports water- ink printing and color fastness of grade 4 or above610.
Second, mainstream composite process classification
Type Process Characteristics Applicable scenarios
Bubble composite kraft paper Bubble diameter 5-25mm optional, buffering capacity is positively correlated with thickness, and has transparent visibility (transmittance > 80 E-commerce express delivery, clothing handicraft packaging17
saudi-arabia PE spray composite kraft paper Single side/double side spray covering polyethyl (PE), resistant to temperature -20℃~80℃, moisture-proof cost is 30% lower than aluminum foil composite 30%, daily product sealed packaging69
Aluminum foil composite kraft paper The best barrier (transparency < 0.5 cm³/(m²·24h, can saudi-arabia vacuum packaging, suitable for high-demand scenarios such as medical devices410
Third, key indicators for purchasing
Base material basis weight matching
It is necessary to select kraft paper with surface smoothness ≥ 50s to avoid bleeding (suitable for LOGO, barcode)613.
Fourth, typical application scenarios
saudi-arabia E-commerce logistics bubble composite kraft paper: Using yellow/ composite bubble bags (size 20×30cm to 40×50cm), the cost per piece is 0.5-1.2 y, reducing the transport damage rate by >40%17.
Precision instruments: Aluminum foil composite bag anti-static coating (surface resistance 0⁶-10⁹Ω), protecting sensitive components such as circuit boards49.
Outdoor gear packaging: PE spray kraft paper bag (IPX grade waterproof) with heat-sealed mouth design, suitable for camping gear, spare clothing storage10.
Note: The choice of composite process needs to match the sealing equipmentsuch as saudi-arabia hot seal machine temperature suggestion 150-180℃); it is recommended to avoid direct sunlight storage for bubble film composite to prevent aging of the bubble layer.
