Highly Effective Air Barrier Extends Freshness By Up To 10 Times
The dreaded summer solstice is here, and the whole country is in "barbecue" mode. Under the scorching sun, are all you brave souls starting to reduce your outings and increase your food stockpiles? With high-temperature warnings in effect, are you stuffing all your food into the refrigerator to extend its shelf life? Usually, after two or three days, food in the refrigerator will gradually lose moisture and lose its freshness, eventually most of it will spoil. Perhaps you've also encountered these problems: opened crispy sunflower seeds become soggy overnight? Leftover watermelon covered with plastic wrap still causes diarrhea the next day? Ultimately, it's not your fault; it's all the air's fault. Moisture in the air makes food damp, and ubiquitous bacteria cause it to slowly rot. So how can we extend freshness several times over while maintaining its original flavor? Today, we bring you a convenient and high-quality home solution: PA+PE vacuum food storage bags!
What exactly are the advantages of vacuum food storage bags? High-quality vacuum-sealed food storage bags are made from BOPA, a long-lasting functional film material with excellent barrier properties, puncture resistance, and flexibility, combined with other materials. This effectively isolates oxygen and moisture, eliminating the conditions for microbial survival, preventing spoilage, and preserving food freshness for longer. Simultaneously, it ensures the vacuum bag remains airtight and doesn't bulge for extended periods, allowing time to preserve deliciousness.
We conducted a preservation comparison: a piece of fresh meat was cut into two equal-sized pieces. One was placed in a regular plastic bag, and the other in a vacuum bag. Both were then placed in the refrigerator's crisper drawer and left for 5 days. The meat in the plastic bag had developed a sour smell, and its color was less vibrant than the meat in the vacuum bag. The vacuum seal, however, remained almost unchanged, maintaining its vacuum state effectively. Isolating air and preventing leakage and bulging significantly extends the shelf life.
Data shows that fresh meat, fish, ham, and biscuits, when stored under vacuum conditions, have approximately 3 times longer shelf life at room temperature, 5 times longer under refrigeration, and 10 times longer under freezing.
Excellent puncture resistance, durable high and low temperature protection to prevent bag breakage
Leftover meat, poultry, fish, and other processed foods are easily damaged when frozen and then removed from the freezer, leading to a shortened shelf life, discoloration, and flavor transfer. BOPA vacuum bags offer excellent puncture resistance, easily handling hard frozen products or frozen items with bones or spiky edges. BOPA is suitable for temperatures ranging from -60℃ to 150℃, maintaining an advantage over other materials at low temperatures, ensuring the bags don't become brittle and break after freezing. They can be safely used in both regular household refrigerators and cold chain freezers.
From meat, grains, and snacks to easily oxidized souvenirs, it can pack them all!
Many foods prone to insect infestation, oxidation, mold, and moisture (especially cooked foods), including Wuhan Zhou Hei Ya (a type of braised duck), Wufangzhai Zongzi (sticky rice dumplings), Dezhou Braised Chicken, and ready-to-eat crayfish, are now transported long distances using vacuum packaging. Vacuum packaging is perfectly suited for both large factory heat-sealing machines and small household heat-sealing machines.
Meat & Ready-to-Eat Foods
Meat is highly perishable. Vacuum-pack it and refrigerate; it will last a week if not frozen, and a year if frozen!
Ready-to-eat snacks that are inconvenient to store? Put them in vacuum bags, and they'll still taste the same after a while.
Grains, Fruits, Vegetables, and Dry Goods
Grains are prone to mold or insects. Vacuum bags protect them from high temperatures and humidity. Lots of vegetables will rot if not properly stored.
Souvenirs
Don't let your graduation certificate turn yellow and moldy, don't let your valuable DSLR camera get damp and lose its sharpness, or your first award medal fit here.
Changsu BOPA film is safe, non-toxic, and environmentally friendly, with superior overall performance. It is widely used in food, daily chemicals, pharmaceuticals, new energy vehicles and other fields, making it a leading film material for the future.
