Product Features
Core Advantages
High Vacuum Degree
Black embossed vacuum bags are made from high-density materials, which can achieve a high level of vacuum, maximizing the extraction of air and other gases to extend the shelf life of food.
Strong Oxygen Barrier
The vacuum bags with good sealing properties can effectively isolate air and oxygen, preventing food oxidation and spoilage, and preserving its original flavor and nutrition.
High-Temperature Resistance
The material has excellent heat resistance, suitable for vacuum packaging of food after high-temperature sterilization and cooking, effectively killing bacteria and extending the shelf life.
Good Anti-seepage Performance
It has a good airtight seal, which can prevent moisture and acidic substances from the outside from penetrating, protecting the freshness and original taste of the food.
Easy to Use
The vacuum packaging system is simple to operate. Just place the food into the bag, seal the edges, vacuum, and seal the borders to preserve for a long time.
Wide Temperature Range Applicability
Vacuum bags made of different materials can be used in a temperature range of -30°C to 100°C, meeting the requirements for freezing, room temperature, and high-temperature processing, with a broad range of applications.
High Cost-Effectiveness
The price of vacuum bags and vacuum packaging machines is relatively low, but they can significantly extend the shelf life of food, reduce waste, and offer high economic benefits, making them suitable for use in food production enterprises.

Frequently Asked Questions
FAQWhat are the dimensional and width deviations for these vacuum bags?
The standard deviation limit for our vacuum bags is ±5 mm, and the width deviation is also maintained within ±5 mm. For heat seal width deviation, it is strictly controlled within ±2 mm.
What is the peel strength and heat seal strength of the materials?
The peel strength values are PET/AL ≥ 4.5N, AL/NY ≥ 5.2N, and NY/PE ≥ 6.3N. The heat seal strength measures at longitudinal ≥ 95N and transverse ≥ 96N, ensuring excellent structural integrity.
What temperature range can these vacuum bags withstand?
These vacuum bags are highly versatile and can be safely used across a broad temperature range of -30°C to 100°C. This makes them ideal for both freezing and high-temperature sterilization or cooking.
Why do black embossed vacuum bags offer a high vacuum degree?
They are manufactured from high-density materials designed specifically to maximize air extraction. This high level of vacuum prevents oxidation, seals out moisture, and significantly extends food shelf life.
Are these vacuum bags cost-effective for commercial food production?
Yes, they are highly cost-effective. Both the bags and the compatible vacuum packaging machines are reasonably priced, allowing food production enterprises to reduce waste and optimize preservation costs.
