opp自封袋与PE自粘袋有什么区别？

一、定义与用途

1、 Definition and purpose

，我们来明确一下opp自封袋与PE自粘袋的定义与主要用途。

Firstly, let's clarify the definitions and main uses of OPP self sealing bags and PE self-adhesive bags.

1. OPP自封袋：

1. OPP self sealing bag:

OPP自封袋，全称为双向拉伸聚丙烯自封袋，采用聚丙烯材料制作而成。由于其透明度高、密封性好、强度高，常被用于食品、饰品、衣物等包装。其自封结构可方便地保存物品，避免二次污染。

OPP self sealing bag, also known as biaxially stretched polypropylene self sealing bag, is made of polypropylene material. Due to its high transparency, good sealing, and high strength, it is often used for packaging food, jewelry, clothing, and other products. Its self sealing structure can conveniently store items and avoid secondary pollution.

2. PE自粘袋：

2. PE self-adhesive bag:

PE自粘袋，全称为聚乙烯自粘袋，主要采用聚乙烯材料制作。其特点是轻便、柔韧、防水、防潮，适用于包装各种小饰品、贴纸、卡片等小物品。由于其自粘性，可轻松封闭袋口，保持物品的整洁与卫生。

PE self-adhesive bag, also known as polyethylene self-adhesive bag, is mainly made of polyethylene material. Its characteristics are lightweight, flexible, waterproof, and moisture-proof, suitable for packaging various small items such as accessories, stickers, cards, etc. Due to its self-adhesiveness, it can easily seal the bag opening, keeping items clean and hygienic.

二、材料与特性

2、 Materials and characteristics

在材料与特性方面，opp自封袋与PE自粘袋也存在一定差异。

In terms of materials and characteristics, there are also certain differences between OPP self sealing bags and PE self-adhesive bags.

1. OPP自封袋：

1. OPP self sealing bag:

OPP自封袋采用聚丙烯材料，具有较高的拉伸强度和冲击强度，因此其耐用性较好。同时，由于聚丙烯是一种结晶性聚合物，其热封性能优良，可在较高温度下进行热封操作。此外，OPP自封袋的透明度高，能清晰展示包装内的物品，便于顾客选购。

The OPP self sealing bag is made of polypropylene material, which has high tensile and impact strength, so its durability is good. Meanwhile, as polypropylene is a crystalline polymer, it has excellent heat sealing performance and can be used for heat sealing operations at higher temperatures. In addition, OPP self sealing bags have high transparency and can clearly display the items inside the packaging, making it easy for customers to choose.

2. PE自粘袋：

2. PE self-adhesive bag:

PE自粘袋则采用聚乙烯材料，其柔韧性较好，可在低温下使用。同时，聚乙烯具有优良的防水性和防潮性，能有效地保护包装内的物品不受潮、不被水侵蚀。此外，PE自粘袋的自粘性能强，可轻松封闭袋口，且粘合强度高，不易撕裂。

PE self-adhesive bags are made of polyethylene material, which has good flexibility and can be used at low temperatures. Meanwhile, polyethylene has excellent waterproof and moisture-proof properties, which can effectively protect the items inside the packaging from moisture and water erosion. In addition, PE self-adhesive bags have strong self-adhesive properties, can easily seal the bag opening, and have high adhesive strength, which is not easy to tear.

三、外观与规格

3、 Appearance and specifications

在外观与规格方面，opp自封袋与PE自粘袋也有所不同。

In terms of appearance and specifications, OPP self sealing bags and PE self-adhesive bags are also different.

1. OPP自封袋：

1. OPP self sealing bag:

OPP自封袋的外观较为透明，具有良好的光泽度。其规格多样，常见的有15cmx20cm、18cmx25cm等，可根据实际需求进行选择。由于其封口设计较为平整，在使用过程中不易出现开口不齐、撕裂等问题。

The appearance of the OPP self sealing bag is relatively transparent and has good glossiness. It has a variety of specifications, commonly including 15cmx20cm, 18cmx25cm, etc., which can be selected according to actual needs. Due to its flat sealing design, it is less prone to problems such as uneven opening and tearing during use.

2. PE自粘袋：

2. PE self-adhesive bag:

PE自粘袋的外观多为乳白色或透明状，具有一定的柔韧性。其规格相对较小，常见的有8cmx12cm、10cmx15cm等。由于其自粘性能强，在使用过程中可轻松封闭袋口，保持整洁美观。同时，PE自粘袋的设计也较为简洁明了，易于操作使用。

The appearance of PE self-adhesive bags is mostly milky white or transparent, with a certain degree of flexibility. Its specifications are relatively small, commonly including 8cmx12cm, 10cmx15cm, etc. Due to its strong self-adhesive ability, the bag opening can be easily closed during use, maintaining cleanliness and aesthetics. Meanwhile, the design of PE self-adhesive bags is also relatively simple and clear, making them easy to operate and use.

四、使用方法与注意事项

4、 Usage and precautions

在使用方法与注意事项方面，opp自封袋与PE自粘袋也有所不同。

In terms of usage methods and precautions, OPP self sealing bags and PE self-adhesive bags are also different.

1. OPP自封袋：

1. OPP self sealing bag:

在使用OPP自封袋时，需注意以下几点：，应选择合适的规格，确保能容纳所需包装的物品；其次，由于其热封性能优良，在使用热封机进行热封时，应调整好温度和时间，避免过度热封导致袋子变形；后，在使用过程中应避免尖锐物品划伤袋子表面，以免影响其美观和使用寿命。

When using OPP self sealing bags, attention should be paid to the following points: first, choose the appropriate specifications to ensure that they can accommodate the required packaging items; Secondly, due to its excellent heat sealing performance, when using a heat sealing machine for heat sealing, the temperature and time should be adjusted to avoid excessive heat sealing causing deformation of the bag; During use, sharp objects should be avoided from scratching the surface of the bag to avoid affecting its appearance and service life.

2. PE自粘袋：

2. PE self-adhesive bag:

使用PE自粘袋时，需注意以下几点：，应选择合适的规格和颜色；其次，在使用前应表面污垢和水分；后，由于其自粘性能强，在使用过程中应避免过度拉扯导致撕裂。同时，应注意避免与尖锐物品接触袋子表面。

When using PE self-adhesive bags, attention should be paid to the following points: first, appropriate specifications and colors should be selected; Secondly, surface dirt and moisture should be removed before use; Afterwards, due to its strong self-adhesive energy, excessive pulling and tearing should be avoided during use. Meanwhile, attention should be paid to avoiding contact with sharp objects on the surface of the bag.
