Material Selection of Zongzi Bag

Zongzi bag, as the traditional packaging of the Loong Boat Festival, not only carries the festivities and blessings of the festival, but also reflects people's concern for environmental protection and sustainable development. When selecting and using Zongzi bags, attention should be paid to their materials, design, functions and environmental significance to create a better, healthy and environmentally friendly festival atmosphere.

Zongzi bags are made of a variety of materials to meet different packaging needs, shelf life requirements and environmental standards. The following are some common Zongzi bag materials and their characteristics:

1、 Traditional materials

Paper:

Kraft paper: It has a tough texture, is wear-resistant, and has waterproof properties. It is often used to make traditional Zongzi packaging bags, giving people a simple and natural feeling.

Glutinous rice paper: It is light, thin and transparent, and can be eaten directly. It is often used to wrap small Zongzi or as an inner packaging material to increase the hygiene and appreciation of food.

Fabric:

Cotton cloth: soft, breathable, often used in hand-made Zongzi bags, with a strong flavor of folk handicrafts.

Linen: wear-resistant, durable, breathable and moisture-proof, suitable for family or small workshop Zongzi packaging.

2、 Modern materials

Plastic:

Polyethylene (PE): Low price, good toughness and waterproof performance, but poor heat resistance, not suitable for high temperature cooking. It is often used to make disposable Zongzi packaging bags.

Polypropylene (PP): high temperature resistance, high mechanical strength, can withstand high temperature cooking, suitable for packaging Zongzi that needs high temperature treatment. At the same time, PP material also has good moisture resistance, which can protect Zongzi from moisture damage.

Polyester (PET): high transparency, high strength, good barrier performance, can effectively prevent the entry of oxygen and water, thus maintaining the freshness and taste of Zongzi. PET material also has good printing performance, which can print clear patterns and text on packaging bags, enhancing the attractiveness of products.

Nylon: high strength, good wear resistance, high barrier performance and high temperature resistance, which can effectively protect Zongzi from the impact of the external environment. At the same time, nylon packaging bags also have good stretch and resilience, which can meet the packaging needs of Zongzi in different shapes and sizes.

Degradable materials:

PLA (Polylactic Acid): A biodegradable material derived from resources such as corn starch. The Zongzi bag made of PLA material can be naturally degraded after use to reduce environmental pollution.

Starch based materials: degradable materials made of starch as the main raw material also have good biodegradability, and are suitable for packaging Zongzi with environmental requirements.

3、 Material selection suggestions

Select according to the type of Zongzi:

For Zongzi that need high temperature cooking, such as fresh meat zongzi, bean paste zongzi, it is recommended to choose high temperature resistant PP or nylon materials.

For Zongzi without high temperature treatment, such as alkaline water zongzi, sweet zongzi, etc., PE or PET materials can be selected.

Considering environmental requirements:

When selecting Zongzi bag materials, priority should be given to environmental performance, and biodegradable or recyclable materials should be selected to reduce environmental pollution.

Focus on cost-effectiveness:

According to the production scale, sales price and other factors, reasonably select the cost-effective Zongzi bag materials. Minimize production costs while maintaining product quality.

To sum up, the material selection of Zongzi bags should be comprehensively considered according to the type of Zongzi, environmental protection requirements, cost-effectiveness and other factors. By selecting appropriate materials, we can make beautiful and practical Zongzi packaging bags to meet the different needs of consumers.
