opp自封袋與PE自粘袋有什么區別？

一、定義與用途

1、 Definition and purpose

，我們來明確一下opp自封袋與PE自粘袋的定義與主要用途。

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，全稱為雙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、強度高，常被用于食品、飾品、衣物等包裝。其自封結構可方便地保存物品，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，全稱為聚乙烯自粘袋，主要采用聚乙烯材料制作。其特點是輕便、柔韌、防水、防潮，適用于包裝各種小飾品、貼紙、卡片等小物品。由于其自粘性，可輕松封閉袋口，保持物品的整潔與衛生。

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、材料與特性

2、 Materials and characteristics

在材料與特性方面，opp自封袋與PE自粘袋也存在一定差異。

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，具有較高的拉伸強度和沖擊強度，因此其耐用性較好。同時，由于聚丙烯是一種結晶性聚合物，其熱封性能優良，可在較高溫度下進行熱封操作。此外，OPP自封袋的透明度高，能清晰展示包裝內的物品，便于顧客選購。

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自粘袋則采用聚乙烯材料，其柔韌性較好，可在低溫下使用。同時，聚乙烯具有優良的防水性和防潮性，能有效地保護包裝內的物品不受潮、不被水侵蝕。此外，PE自粘袋的自粘性能強，可輕松封閉袋口，且粘合強度高，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、外觀與規格

3、 Appearance and specifications

在外觀與規格方面，opp自封袋與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自封袋的外觀較為透明，具有良好的光澤度。其規格多樣，常見的有15cmx20cm、18cmx25cm等，可根據實際需求進行選擇。由于其封口設計較為平整，在使用過程中不易出現開口不齊、撕裂等問題。

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自粘袋的外觀多為乳白色或透明狀，具有一定的柔韌性。其規格相對較小，常見的有8cmx12cm、10cmx15cm等。由于其自粘性能強，在使用過程中可輕松封閉袋口，保持整潔美觀。同時，PE自粘袋的設計也較為簡潔明了，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、使用方法與注意事項

4、 Usage and precautions

在使用方法與注意事項方面，opp自封袋與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自封袋時，需注意以下幾點：，應選擇合適的規格，確保能容納所需包裝的物品；其次，由于其熱封性能優良，在使用熱封機進行熱封時，應調整好溫度和時間，避免過度熱封導致袋子變形；后，在使用過程中應避免尖銳物品劃傷袋子表面，以免影響其美觀和使用壽命。

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自粘袋時，需注意以下幾點：，應選擇合適的規格和顏色；其次，在使用前應表面污垢和水分；后，由于其自粘性能強，在使用過程中應避免過度拉扯導致撕裂。同時，應注意避免與尖銳物品接觸袋子表面。

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.
