Amid the upgraded Plastic Restriction Order and the trend of eco-friendly consumption, paper bags have become a core alternative to plastic packaging, thanks to their characteristics of "biodegradability, customizability, and strong scenario compatibility." In 2024, the domestic paper bag market scale exceeded 18 billion yuan, with scenario-specific paper bags (such as oil-proof paper bags and gift paper bags) accounting for 65% of sales. Their precise adaptation to needs in different fields is driving the packaging industry toward "low-carbon practicality."
In retail scenarios like supermarkets and clothing stores, paper bags excel in "load-bearing capacity + brand display":
Shopping paper bags made of 80-120g kraft paper have a single-bag load-bearing capacity of 5-8kg (vs. 3-5kg for ordinary plastic bags), suitable for loading clothing, daily necessities, and other categories. Data from a chain clothing store shows that the reuse rate of kraft paper shopping bags reaches 42% (vs. only 15% for plastic bags);
Their surface supports full-color printing (ink adhesion ≥95%), allowing brand logos and promotional information to be printed—turning them into "mobile advertising carriers." Consumers’ favorability toward paper bags with brand logos increases by 38%.
Additionally, the foldable design reduces the storage volume of empty bags by 70%, saving store warehouse space and meeting the "efficient turnover" needs of the retail industry.
The core demand for paper bags in the food and beverage sector is "leakage prevention," and specialized oil-proof paper bags address this through technological upgrades:
The inner layer is coated with a 15-20μm food-grade PE film, resulting in an oil penetration rate ≤0.5%—suitable for oily foods like fried chicken and hamburgers. Testing by a food delivery platform shows that the oil leakage rate of oil-proof paper bags is only 3% (vs. 35% for ordinary paper bags);
Some paper bags add 0.5mm-diameter ventilation holes to prevent food from becoming soggy due to trapped heat, increasing the texture retention rate of crispy foods (such as French fries and bread) by 60%.
Meanwhile, their biodegradable nature fits the "single-use after consumption" scenario of the food industry—they are fully biodegradable within 90 days in natural environments, reducing environmental pollution by 98% compared to non-biodegradable plastic bags.
In scenarios like holiday gifts and souvenirs, the "customizable design" of paper bags meets emotional needs:
Made of 150-200g coated paper or specialty paper, they support processes like gold stamping and embossing. Data from a gift shop shows that customized gift paper bags increase the product premium space by 25%;
Paired with accessories like ribbons and tags, they fit different themes (birthdays, festivals, etc.). When consumers choose gifts with customized paper bags, their "sense of ritual" score reaches 8.9/10.
Moreover, the foldable handle design (load-bearing ≥2kg) prevents hand strain during carrying, enhancing comfort and making them the first choice for high-end gift packaging.
In office scenarios, the "classified storage + eco-friendliness" of paper bags meets daily needs:
A4-sized document paper bags (made of 60-80g writing paper) can store documents and receipts, with a label area for easy categorization—improving office document organization efficiency by 40%;
Kraft paper archive bags have strong aging resistance (no obvious yellowing after 5 years of storage), suitable for long-term archive storage;
Their recyclability rate reaches 100%. After an enterprise replaced plastic file bags with kraft paper ones, it reduced annual plastic usage by 2.3 tons, aligning with the corporate goal of "green office."
| Application Scenario | Paper Bag Type | Core Adaptation Points | Key Indicators/User Feedback |
|---|---|---|---|
| Retail Consumption | 80-120g Kraft Paper Shopping Bags | Load-bearing 5-8kg, brand printing | Reuse rate 42%, favorability +38% |
| Food Delivery | PE-Coated Oil-Proof Paper Bags | Oil/water resistance, ventilation for freshness | Oil leakage rate 3%, texture retention +60% |
| Gift Packaging | 150-200g Custom Gift Paper Bags | Decorative processes, sense of ritual | Product premium +25%, ritual score 8.9/10 |
| Office Storage | 60-80g Document/Archive Paper Bags | Categorization labels, aging resistance | Organization efficiency +40%, 100% recyclable |
Currently, paper bags are developing toward "functional upgrading":
Food paper bags with antibacterial coatings (antibacterial rate ≥99%) are suitable for fresh food scenarios;
Retail paper bags with smart QR codes (supporting traceability and coupon redemption) enhance interactivity. In 2024, sales of such innovative paper bags grew by 58% year-on-year.
As a dual carrier of "eco-friendliness + practicality," the multi-scenario adaptability of paper bags not only meets needs in different fields but also becomes a key driver for the low-carbon transformation of the packaging industry.
