　　随着生活节奏加快，速冻食品成为了许多家庭冰箱里的常客。饺子、汤圆、鸡块、薯条……琳琅满目的冷冻美食，只需简单加工就能上桌，方便又省时。我们深知包装袋对食品品质的重要性。一款合格的冷冻食品包装袋，不仅是容器，更是食品的“保护神”。让我们来了解冷冻食品包装袋的那些专业知识！

　　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冷冻包装袋的“核心技术指标”

　　01 Core technical indicators of frozen packaging bags

　　1. 低温抗冲击性

　　1. Low temperature impact resistance

　　优质冷冻袋必须通过-40℃低温落镖冲击测试。采用进口线性低密度聚乙烯（尝尝顿笔贰）原料，使包装袋在极低温环境下仍保持柔韧性，避免运输途中破损。

　　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. 水蒸气透过率（WVTR）

　　2. Water Vapor Transmission Rate (WVTR)

　　这是衡量防脱水性能的关键指标！叁层共挤吹膜技术，水蒸气透过率低于5驳/尘?·24丑，有效防止食品冻伤和脱水。

　　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. 氧气透过率（OTR）

　　3. Oxygen Transmittance Rate (OTR)

　　多层复合结构包装袋的氧气透过率可控制在100肠尘?/尘?·24丑·补迟尘以下，大幅延缓食品氧化变质。

　　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如何辨别优质冷冻食品包装袋？

　　How to identify high-quality frozen food packaging bags?

　　一看：透明度

　　At first glance: Transparency

　　优质原料生产的袋子透明度高，颗粒均匀无黑点。

　　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

　　柔韧有弹性，揉搓无脆响（低温下测试更明显）。

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

　　叁闻：气味

　　Three smells: odor

　　无刺鼻异味，只有淡淡的塑料原料味。

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

　　四试：密封性

　　Four tests: sealing performance

　　装水倒置十分钟不漏水，冷冻24小时不开裂。

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