Labels are an essential channel for identifying products and providing information. Although the label is small, its role cannot be ignored. The label on the product can not only regulate the product’s safety but also prevent counterfeiting and protect the rights and interests of consumers. त्यामुळे, the label should be attached to the object as firmly as possible in order to convey the message successfully. Once it falls off, the effectiveness of the label will be lost, and people will not be able to receive information through the label.
Despite the passage of time and environmental changes, even high-quality labels with strong adhesives will eventually fall off. Especially in the cold winter, तापमान कमी झाल्यामुळे लेबलची चिकटपणा कमकुवत होईल. परंतु तरीही आम्ही काही पद्धतींद्वारे लेबल बाँडिंग वेळ वाढवण्याचा प्रयत्न करू शकतो. This article will focus on several reasons why labels are easy to fall off and the corresponding solutions, प्रामुख्याने लेबल पृष्ठभाग सामग्रीच्या पैलूंमधून, चिकट गुणवत्ता, उत्पादन स्वतः, स्टोरेज वातावरण, आणि उत्पादन प्रक्रिया.
1. लेबल पृष्ठभाग साहित्य
जेव्हा आम्ही लेबल सामग्री निवडतो, आम्ही उत्पादन क्षेत्र विचारात घेतले पाहिजे, साहित्य, स्टोरेज वातावरण, आणि इतर घटक. लेबल फेस स्टॉक उत्पादनाच्या प्रकार आणि गरजांसाठी योग्य नसल्यास, त्याचा जास्तीत जास्त फायदा घेणे कठीण होईल. सर्वसाधारणपणे बोलणे, लेबलची लवचिकता सुधारण्यासाठी आम्ही एक मऊ लेबल सामग्री निवडू. उदाहरणार्थ, मऊ प्लॅस्टिकच्या बाटल्यांसाठी पीई आणि पीव्हीसी सारख्या मऊ स्व-चिकट सामग्रीचा वापर केला जाऊ शकतो, आणि पीईटी आणि बीओपीपी सामग्री कठोर बाटल्यांसाठी वापरली जाऊ शकते.
2. चिकट गुणवत्ता
Improving the stickiness of labels is the most direct and effective way to prevent labels from falling off. त्यामुळे, we need to choose the appropriate adhesive material according to different objects. The glue used for labels is usually water glue, hot glue, oil glue. These three types of glue have their own advantages and disadvantages.
Water glue uses water as a solvent, and the glue itself is non-flammable, non-toxic, odorless, and environmentally friendly. तोटे: long curing time, weak water resistance, poor initial viscosity, freezing at low temperature will cause paper to wrinkle or curl.
Hot glue is solid at normal temperature, and when heated and melted to a certain temperature, it becomes able to flow. Advantages: hot glue has high viscosity, can quickly produce bonding, and has good storage stability. तोटे: poor heat resistance, will decompose under continuous heating, high energy consumption.
Oil glue uses organic solvents as solvents, which has short curing time, less energy consumption, good water resistance, and higher initial bonding strength than water glue. तोटे: not environmentally friendly, the solvent is volatile, and the glue itself is flammable.
त्यामुळे, selecting the appropriate glue type and material according to the needs of the product can effectively solve the problem of label peeling off.
3. Product Itself
The roughness and flatness of the surface of the object to be pasted also have a great influence on the labeling effect. If the surface of the product is rough, the label is prone to warping and falling off. याव्यतिरिक्त, if there are impurities such as oil, water droplets, and dust on the surface, it will also cause the label to become less sticky. लेबल लावण्यापूर्वी उत्पादन स्वच्छ पुसून ही समस्या टाळता येऊ शकते.
याव्यतिरिक्त, उत्पादनास चांगले बसविण्यासाठी, लेबलची उलगडलेली पृष्ठभाग एक समतल असावी. जर लेबलची पृष्ठभाग अनरोलिंग केल्यानंतर दोन्ही दिशांना वक्र असेल, लेबल लावल्यानंतर लेबल सहजपणे सुरकुत्या पडेल. बाटलीच्या शरीरावर लेबलिंग करताना, गोलाकार स्थिती शक्य तितक्या टाळणे आवश्यक आहे. अटळ असेल तर, विकृत क्षेत्र टाळण्यासाठी लेबलच्या तळाला चाप बनवता येते. लेबलचा आकार बदलल्याने केवळ वॅपिंग टाळता येत नाही, परंतु सौंदर्याची भावना देखील वाढवा.
4. स्टोरेज वातावरण
भिन्न लेबल सामग्रीमध्ये वापराच्या तापमान श्रेणी दर्शविणारे मापदंड असतात. सभोवतालच्या तापमानाचा लेबलच्या आयुष्यावर विशिष्ट प्रभाव असतो. उदाहरणार्थ, जर उत्पादनाचे स्टोरेज तापमान खूप कमी असेल, गोंद फ्रॉस्टबिट करणे सोपे आहे, आणि मग लेबल पेपरची चिकटपणा गमावणे आणि पडणे सोपे आहे. त्यामुळे, गोंदची तरलता राखण्यासाठी, किमान लेबलिंग तापमानापेक्षा जास्त वातावरणात लेबल केलेल्या गोंदाचे प्रारंभिक स्निग्धतेपासून अंतिम स्निग्धतेत रूपांतर करणे आवश्यक आहे..
जर तुम्हाला लेबलचे आयुष्य वाढवायचे असेल, लेबल जेथे आहे त्या वातावरणाने थेट सूर्यप्रकाश शक्यतो टाळावा, आणि आर्द्रतेपासून संरक्षण करा, सूर्य, उच्च तापमान आणि अति-कमी तापमान. स्वतंत्रपणे साठवलेले स्व-चिपकणारे लेबल पेपर ओलावा-प्रूफ पेपर किंवा फिल्म पॅकेजिंगसह सीलबंद केले पाहिजे, रोल सरळ रचले पाहिजेत, आणि पत्रके सपाट ठेवली पाहिजेत. लेबलच्या प्रत्येक वापरानंतर, it should be sealed again to ensure better storage conditions.
5. Manufacturing Process
Different labeling processes will also affect the life of the label. One of the processes of label application is to apply proper pressure to the label through the labeling machine to ensure that the label fits perfectly with the labeling machine. For different labeling surfaces and requirements, we should choose different labeling machines, such as sponge wheels, pulleys, labeling plates, इ. An appropriate labeling pressure can not only meet the pressure-sensitive characteristics of the self-adhesive label but also discharge the air between the label and the surface to be pasted so that the label can be firmly and smoothly attached. याव्यतिरिक्त, when labeling, it is also necessary to pay attention to the cleanliness of the surface of the object to be pasted, so as to ensure the stickiness of the label and the smoothness after bonding.
It usually takes 24 hours for the stickiness of self-adhesive label materials to gradually reach the maximum value after labeling is completed. At this time, it is not advisable to immediately place the newly labeled product in an environment with a large temperature difference, even if the environment meets the temperature range of the self-adhesive material. Otherwise, the performance of glue viscosity will be affected. उदाहरणार्थ, film labels and containers will expand and contract due to temperature changes, while paper labels are more prone to the deformation of paper fibers due to moisture or loss of water. त्यामुळे, it needs to be at a suitable ambient temperature during the labeling process and after the labeling is complete.
If you can’t judge the labeling method by yourself, you only need to provide us with a sample, and we can pass different tests to provide you with the best solution. According to your product characteristics and storage requirements, we will recommend the most optimal label, its application method and usage details for you.
