外卖打包袋选择“四丝”厚度是否合适，需结合具体使用场景和商家需求综合判断：

　　Whether the thickness of the "four silk" packaging bag for takeout is appropriate depends on the specific usage scenario and the needs of the merchant

　　基础防漏性不足

　　Insufficient basic leak prevention

　　四丝厚度（约0.04毫米）的打包袋通常仅适用于轻量级物品，如小份餐品或非液体食品。对于汤面、粥品、奶茶等液体类商品，四丝厚度无法满足防漏要求，容易导致渗漏。

　　A packaging bag with a thickness of about 0.04 millimeters is usually only suitable for lightweight items such as small meals or non liquid food. For liquid products such as Noodles in soup, Congee and milk tea, the thickness of four filaments cannot meet the leak proof requirements, which is easy to lead to leakage.

　　适用场景建议

　　Suggested Applicable Scenarios

　　炸鸡、烧烤类 ：可选用带防油纸内层的复合袋，四丝厚度能满足防油需求，同时搭配热压封边工艺提升耐用性。

　　Fried chicken and barbecue products: composite bags with an inner layer of oil resistant paper can be selected, with a thickness of four threads to meet oil resistance requirements, and combined with hot pressing edge sealing technology to enhance durability.

　　普通快餐类 ：若仅用于非液体食品（如汉堡、沙拉等），四丝厚度可满足基本需求，但需注意底部和侧边避免拼接缝。

　　Ordinary fast food: If only used for non liquid foods (such as hamburgers, salads, etc.), a thickness of four strands can meet basic needs, but attention should be paid to avoiding seams at the bottom and sides.

　　选购注意事项

　　Purchase precautions

　　优先选择“加厚PE材质+热压封边”的产品，厚度至少8丝（如4丝+4丝组合）更耐用。

　　Priority should be given to products made of "thickened PE material+hot pressed edge sealing", with a thickness of at least 8 threads (such as a combination of 4 threads and 4 threads) for greater durability.

　　对比不同品牌和规格，确保封边工艺和材质符合食品级标准。

　　Compare different brands and specifications to ensure that the edge sealing process and materials meet food grade standards.

　　总结 ：四丝厚度打包袋在特定场景下（如非液体快餐）可用，但液体类食品或高复购率需求场景需选择更厚、防漏性更强的产品。

　　Summary: Four thread thickness packaging bags can be used in specific scenarios (such as non liquid fast food), but for liquid food or high repurchase rate demand scenarios, thicker and more leak proof products should be selected.
