Vacuum packaging bag

This product inhibits microbial growth by excluding oxygen inside the bag, reduces the rate of food oxidation and deterioration, and maintains a humid environment to slow down the respiration of fruits and vegetables, thereby extending the shelf life. Some models are equipped with an air extraction device, consisting of an air extraction cover, a sealing plate bracket, and a matching air extraction cylinder, which achieves airtight sealing through threaded connection

Kraft paper bag

Kraft paper self-sealing bags, also known as kraft paper zipper bags or kraft paper zip-lock bags, are non-toxic, odorless, and pollution-free, meeting national environmental standards. They are highly durable and environmentally friendly, making them one of the most popular eco-friendly packaging materials internationally. The use of kraft paper to make kraft paper self-sealing bags has become increasingly widespread. When shopping at supermarkets, malls, food stores, health food stores, and other places, products are generally packaged in kraft paper self-sealing bags. These eco-friendly packaging bags have a wide range of applications. They are mainly used for packaging: dried fruits, snack foods, dried meat products, grains, health products, tea, and other food packaging. In some hospitals, to avoid cross-infection, departments cleverly use disposable self-sealing bags to make record protection bags, which has achieved good results.

Snack food bag

This is the most basic and crucial function of snack packaging bags, aimed at ensuring the quality and safety of snacks throughout the entire process from production to consumption.

1. Physical protection: Packaging bags can effectively prevent snacks from being squeezed, impacted, shaken, and other mechanical damages during transportation, storage, and sales, maintaining their intact form

2. Isolated Environment: Through physical barriers, packaging bags can isolate oxygen, water vapor, dust, odors, and pollutants, preventing snacks from becoming damp, moldy, oxidized, or tainted with other flavors, thus maintaining their original flavor, taste, and freshness. For this reason, vacuum packaging, nitrogen-filled packaging, or the addition of desiccants, deoxidizers, and other technologies are often used in packaging

3. Extending shelf life: Through the aforementioned isolation and protection measures, packaging bags significantly extend the shelf life of snacks

Ice pop wrapper

The primary function of the easy-to-tear packaging bag for ice cream is to enhance the user's convenience and experience in opening the package. This design incorporates an easy-to-tear slit on the packaging bag, allowing users to open the package with just a gentle pull, without the need for tools such as scissors, thus making it easier to retrieve and consume the ice cream

Aluminum foil packaging bag

Aluminum foil packaging bags combine the excellent barrier properties of aluminum foil material with the convenience of zipper design, and their main functions include the following aspects:

1. Excellent barrier protection: The aluminum foil layer can effectively block oxygen, moisture, light, and odors, preventing the contents from oxidizing, getting wet, or deteriorating. It is suitable for items with high requirements for storage environment, such as food (meat, tea, nuts), pharmaceuticals, etc

2. Convenient for repeated use: The zipper closure design allows for easy opening and sealing, facilitating multiple access and storage. It is particularly suitable for refrigerator/freezer environments, keeping food fresh and reducing waste

3. Enhanced mechanical protection: Aluminum foil material possesses puncture and tear resistance, effectively protecting the contents from physical damage during transportation or storage

4. Environmental Resistance: Resistant to high temperatures (up to 121℃) and low temperatures (down to -50℃), suitable for freezing, hot filling, or long-term storage scenarios

5. Safety and Environmental Protection: Non-toxic and odorless, meeting food/drug hygiene standards; some designs are reusable or recyclable, reducing environmental pollution

6. Enhance user experience: The zipper structure ensures good sealing, preventing leakage or cross-contamination of contents, while also facilitating portability and identification (such as independent packaging for pharmaceuticals)

Coffee bean packaging bag

The one-way air valve coffee bean packaging bag mainly serves the following purposes:

1. Release of Carbon Dioxide: Coffee beans continue to release carbon dioxide after roasting, a process that may last for days or even weeks. The one-way exhaust valve allows the gas (mainly carbon dioxide) inside the bag to escape, preventing the packaging bag from bulging or rupturing due to excessive internal pressure

2. Blocking external air: The exhaust valve is designed for one-way circulation, allowing only gas to exit from the bag while preventing external oxygen, moisture, etc. from entering the bag. This effectively prevents the oxidation and deterioration of coffee beans, preserving their aroma and flavor

3. Extending the freshness period: By controlling the internal environment of the bag (reducing oxygen exposure and balancing air pressure), the exhaust valve helps to slow down the aging process of coffee beans, thereby extending their flavorful period

4. Assist in judging freshness: When purchasing, gently squeeze the packaging bag to release gas through the exhaust valve and smell its aroma - fresh coffee beans will emit a strong aroma, while stale beans will have a weaker scent
