Issues Of Heat Shrink Film And Their Solutions
When you are shrink wrapping products with heat shrink films, you will realize it is accompanied by various issues. Various terms are used to describe the issues of shrink wrapping, which we will inform you more about them. Such issues are obvious ones, and solving them is easy just by having the machine setting adjusted. You can be required to adjust the temperature, conveyor speed, and air velocity of the tunnel.Their perforations quantity and size have some effects too, depending on the speed of forming the balloon and the speed it uses to collapse when there is a shrinking film. You should analyze the rate of air escaping from the film so you can come up with packages that are best looking. You can start by making the empty package onto the sealer having air in it then squeeze the air to confirm if it has holes for escaping. You can then individually pull each seal to confirm if they are very strong since weak seals will give you poor shrink. The strength of seals depends on pressure, temperature, and time. The film should also be relaxed so you can avoid getting weak seals. Below are some issues associated with heat shrink films packages and the way you can solve them. Heat Shrink Film Issues And Its Solutions 1. Dog Ear Most shrink wrappings experience the problem of dog ear, especially in the retail stores. The dog ears are protruded in a triangular shape in the packaging corner that shows there is no shrinkage. They mostly happen in large areas that have excess film amount before completion of shrinking or in corners. Causes: • Large shrink bag• Improper heat amount• Loud products that have many perforations located in the wrong places• Weak seals or many perforations which allow easy escape of air Solutions: • Adjust tunnel temperature at the monitor package shrink• Use a tighter packaging bag before shrinking• Adjust perforations or add some hole punches• Reduce conveyor speed at the tunnel• Increase the air velocity of the tunnel• Correct perforation amount. 2.Fish Eyes They are oval and round patterns being formed on the package due to poor shrinking and they make the package seem unprofessional. Causes: • Less heat• Wrong air velocity• Bad seals or many perforations Solutions: • Adjust heat temperature to the required amount• Ensure heat source offers required air velocity• Reduce the speed of tunnel conveyor• Use a lighter bag size. 3. Crow’s Feet They are simply wrinkles found at the wrapping package corner. They always appear with dog ears. Causes: • The product corners can have excess films• Less heat Solutions: • Use a thinner shrink film• Lower available air holes or sizes• Lower air being evacuated at the heat shrink film container• Use a smaller bag 4. Angel Hair They are thin shrink film strands between the sealed end and the product that is being sealed at the wrapping film. When it is large at the package, there is no attractiveness. Causes: • Uneven clamp pressures• Low sealing temperatures• Shrink film type• Incomplete sealing• Knife, wire, seal blade being used. Solutions: • Adjust proper temperature to the sealing• Use even clamp pressures• Apply compatible shrinking films 5. Ballooning It can happen when you expose heat shrink films to hot air where the inside air will expand, which makes it be able to gust out, and it will resemble a balloon. Causes: • Perforated holes being poorly positioned• No perforations to evacuate air from the film Solutions: • Use proper perforation• Don't allow more air at the film before you shrink• Use more holes• Properly position holes for the evacuation of air 6. Burn Out They are due to more heat at the heat shrink film that causes tearing or burning as it shrinks. It can cause unwanted holes at the film since bubble package has improper heat.you can detect it in trials then correct before the package shrinks finally. Confirm everything is happening in the tunnel during shrinking. Cause: • Fewer perforations• Slow tunnel conveyor• Package has voids• High temperature Solutions: • Add perforation holes• Increase speed for tunnel conveyor• Reduce temperatures• Shrinking film gauge should be thicker. 7. Hazing When there is a cloudy shrink film after the process, that is called hazing. Mostly it happens in voids when rounded bottles are being wrapped. Cause: • More heat Solutions: • Reduce temperature at the tunnel• Increase conveyor speed 8. Weak Seal Here, the shrink bag sealing line is broken or can have holes. Causes: • High sealing temperature• Sealing line improperly placed• Uneven sealing pressure applied• Dirty sealing blade/base surface• Damaged seal tape/pad• Fast sealing cycle Solutions: • Reduce blade temperature• Place sealing line at the center of the product• Use even sealing blade and confirm the sealing pad is okay• Cleaning the sealing blade/base surface• Replace a damaged sealing tape/pad• Elongate the sealing cycle 9. Bad Seal Position Here, the shrink bag sealing line is not placed at the product’s center. Causes: • Improper sealing conveyor or table height• Improper sealing frame height• Wrong sealing frame blower direction• Large shrinking bag Solutions: • Ensure you reset the sealing table height or its conveyor belt height• Ensure the sealing frame has a reset height• Make sure the shrink tunnel blower direction is placed correctly• Use a tighter shrink bag 10. Crushing The crushing of the product happens when the shrink film crushes it since there is a large shrinking force. Causes: • There might be a high shrink tunnel temperature• Very low shrink tunnel speed or conveyor speed• Very small shrink tunnel bag• Incompatible shrinking film for packing the products Solutions: • Ensure the temperature of the shrink tunnel is decreased• Increase the conveyor speed of the shrink tunnel• Ensure the heat shrink film bag is big• Select the compatible shrink film When having your products packaged with heat shrink film, you need to make sure such issues are not available in your packages and if they are found, then fix them using the provided solutions immediately so you can have an attractive package of good quality. People always like attractive products with no any issues in them.Read More>>
PVC Materials for Building and Construction
The PVC is widely known for its extensive use in building and construction, and they are regarded as the best materials for more than half the century. The PVC has lightweight, strong, versatile, and durable characteristics which makes it ideal in various applications which are as explained below. The PipesThe PVC pipes are famous for more than 60 years when you compare them with traditional material pipes, they offer very valuable energy saving in production, and safe and low distribution cost, lifetime service, and has no maintenance costs. The PVC film sheets can’t get damaged by the environment; hence they only suffer limited breaks compared to other options. The PVC materials are specified widely for the water, drainage, and waste pipeline system since it has a theoretical service over many years of some buried pipes which are still working properly. There is no build-up suffering from PVC pipes and corrosion, scaling, pitting is not also realized. They are known to provide smooth pumping requirements for surface reduction energy. The WindowsPVC film sheets are used to fabricate windows frames from the 1960s. The dramatic growth of the UK too is due to the use of PVC in their windows projects. The PVC windows are durable and tough and have a great lifespan of 35 years which is an accessed period it can last. The PVC windows play an important role mostly in sustainable building and construction since it is regarded as the guide towards specification and they came up achieving higher grades of Aplus and A ratings. The FlooringThe PVC flooring is used over long periods which provide very effective solutions for flooring in private and public constructions both in durable and domestic ideas regardless of the size of the idea. The PVC flooring has got some benefits which may be: • they have a variable thickness• they are easily recycled• they are very durable• they are easily cleaned and installed• they have liberty concerning their aesthetic effects since you can get it in wide patterns and colors. PVC flooring is known to be extensively used in hospitals, housing, and hotels in the entire world. RoofingWhen you reinforce the PVC flooring, you will find it easy to be installed, their maintenance requirements are low, and they have a long-lasting period of 30 years. They may be used in creating ultra-light structures of weight which are web-like. The tensile fabrics of PVC can be used as signatures often. Inflatable StructuresThe inflatable structures are strong and flexible which enables them to be perfectly made. It is hence very versatile plastic that can be relied upon. The Lighter StructuresHaving the latest architecture in textile, you can be able to construct the web-like structures which are capable of withstanding various identical constraints. They are very light which make them holding the ground and have a reduced environmental impact. The emerging trends according to lighter buildings structures which are major inspiration source. The construction and building industry use a large percentage in consuming PVC which has been estimated in above PVC tons that is 4 million in the sector. They are the main polymeric materials to construct and build the industry due to the benefits they offer, and they include:The PVC film sheets are very cost effective materials with a longer lifespan of up to fifty years. It is among the main reasons that make it the best in using the building and construction facilities. It is common that when products catch fire, they release heat, but as for the OVC product, they generate 20000KJ/KG which makes it very superior compared to other materials that may release more heat. PVC film sheets are also considered as safe materials to use when in constructions and buildings. It is safe which concludes that it is never harmful when you compare them with timber products. You only need to take small precautions like covering your face using some masks so you may not suffocate, faint, or feel nausea. The PVC film sheets can’t be compared with timber due to their great benefits which are not applicable when timber is being used. One may opt to use asbestos, fiberglass, or glass reinforced products apart from using PVC sheets but bear in mind that it may give you cancer when you use asbestos. It is hence wise decision to decide to select the PVC sheets which are safe. The PVC film sheets have got favored prices; hence one can easily afford them compared to other traditional materials used in the construction industry. It is always wise to select the PVC film sheets since they are more advantageous in all aspects; hence they lead to proper handling during the construction process.Read More>>
