隨著生活節奏加快，速凍食品成為了許多家庭冰箱里的常客。餃子、湯圓、雞塊、薯條……琳瑯滿目的冷凍美食，只需簡單加工就能上桌，方便又省時。我們深知包裝袋對食品品質的重要性。一款合格的冷凍食品包裝袋，不僅是容器，更是食品的“保護神”。讓我們來了解冷凍食品包裝袋的那些專業知識！

　　With the acceleration of the pace of life, frozen food has become a frequent guest in many households' refrigerators. Dumplings, rice dumpling, chicken nuggets, French fries... a variety of frozen foods can be served simply by processing, which is convenient and time-saving. We are well aware of the importance of packaging bags for food quality. A qualified frozen food packaging bag is not only a container, but also the "protector" of food. Let's learn about the professional knowledge of frozen food packaging bags!

　　01冷凍包裝袋的“核心技術指標”

　　01 Core technical indicators of frozen packaging bags

　　1. 低溫抗沖擊性

　　1. Low temperature impact resistance

　　優質冷凍袋必須通過-40℃低溫落鏢沖擊測試。采用進口線性低密度聚乙烯（LLDPE）原料，使包裝袋在極低溫環境下仍保持柔韌性，避免運輸途中破損。

　　High quality frozen bags must pass the -40 ℃ low-temperature dart impact test. Imported linear low-density polyethylene (LLDPE) raw material is used to maintain the flexibility of the packaging bag in extremely low temperature environments, avoiding damage during transportation.

　　2. 水蒸氣透過率（WVTR）

　　2. Water Vapor Transmission Rate (WVTR)

　　這是衡量防脫水性能的關鍵指標！三層共擠吹膜技術，水蒸氣透過率低于5g/m?·24h，有效防止食品凍傷和脫水。

　　This is a key indicator for measuring anti dehydration performance! Three layer co extrusion blown film technology, with a water vapor transmission rate of less than 5g/m? ·24 hours, effectively preventing food frostbite and dehydration.

　　3. 氧氣透過率（OTR）

　　3. Oxygen Transmittance Rate (OTR)

　　多層復合結構包裝袋的氧氣透過率可控制在100cm?/m?·24h·atm以下，大幅延緩食品氧化變質。

　　The oxygen permeability of multi-layer composite structure packaging bags can be controlled at 100cm?/m? ·Below 24 hours · atm, it significantly delays food oxidation and spoilage.

　　02如何辨別優質冷凍食品包裝袋？

　　How to identify high-quality frozen food packaging bags?

　　一看：透明度

　　At first glance: Transparency

　　優質原料生產的袋子透明度高，顆粒均勻無黑點。

　　The bags produced from high-quality raw materials have high transparency and uniform particles without black spots.

　　二摸：手感

　　Second touch: tactile sensation

　　柔韌有彈性，揉搓無脆響（低溫下測試更明顯）。

　　Flexible and elastic, with no brittle sound when rubbed (more pronounced at low temperatures).

　　三聞：氣味

　　Three smells: odor

　　無刺鼻異味，只有淡淡的塑料原料味。

　　No pungent odor, only a faint smell of plastic raw materials.

　　四試：密封性

　　Four tests: sealing performance

　　裝水倒置十分鐘不漏水，冷凍24小時不開裂。

　　Invert the water for ten minutes without leaking, and freeze for 24 hours without cracking.
