Shrink film – it is everywhere

Manufacturers across the divide continue to produce quality products. We are all too familiar, with the attractive transparent packaging of toys, imported fruits, clothes, pens amongst other things. Unlike the previous times, customers can still have a glimpse into their prospective purchases, carefully examining them without necessarily compromising their state or quality (food).

It is as a result of these demands that the shrink film was developed. In the formative years; we were all accustomed to the brown paper bags which had our tree population on the decline. Subsequent move to the opaque store-name-christened polythene was a further disservice. Then came the perfect solution to all these problems, the shrink film.Initially, the shrink film was exclusively made from PVC (Polyvinylchloride).This is a plastic polymer (third most used plastic in the world) that had the capability of sealing products with a thin layer of plastic sheet. These sheets were often transparent to allow the customer have a view of the product.

The sheet would be wrapped over the product and passed over a heat tunnel or a heat gun. Normally, the length or circumference of the product would be measured, 10% of this value would be added then the sum is divided by two, this would give the size of PVC shrink wrapping to be used. PVC has the ability to shrink by 40% percent giving the packaging a tight grip of the product.

However, with time it was noticed that PVC could release small amounts of hydrogen chloride giving the products a characteristic smell in addition to poisoning. The sealers also would have small carbon deposits. The presence of a plasticizer in PVC had the drawback of hardening and shrinkage during cold weather and extreme stetching with subsequent temperature increases.

These drawbacks meant a suitable shrink film devoid of a plasticizer be developed. Polyolefin was found to have the packaging abilities of PVC but lacked the setbacks that faced the latter. It became a preferred choice of packaging. Offering a stronger seal and fewer odours. Its lack of plasticizer meant no physical changes to the shrink film. It would become the perfect storage solution; all weather .Lack of chlorine in its polymer meant no hydrogen chloride previously characteristic of PVC.

However, while its predecessor PVC enjoys machine compatibility and low cost purchases, polyolefin is the opposite, it remains relatively expensive and hard to use alongside machines.PVC on the other hand remains a suitable choice for manufacturers who don’t deal with edible products. Owing to its cheap price and machine compatibility it is a manufacturers darling.

It is of note that, both polymers are ideal for different packaging purposes. The choice of a shrink wrap is determined by the product, budget and level of technology the producer in question has.

The undeniable fact is, packaging being the cornerstone of branding and advertising can be responsible for high sales volume or the reverse. Manufacturers and producers alike are today faced with the tough task of choosing the ideal packaging material. In the end the functionality of the shrink wrap can only be determined by the manufactures and producers.

Spider Veins – Cause and Treatments

Sometimes, you may have noticed red and blue blood vessels visible through your skin. Have you become a bit worried or embarrassed about them? Do you wonder what they are? They are known as spider veins. Let’s discuss the causes and various treatments of spider vein.

What causes spider veins?
Spider veins are a mild manifestation of venous reflux disease. They are small, tangled groups of blood vessels found just under the skin surface. The veins are slightly dilated, and have the appearance of branches or spider webs, and normally spread out on the legs and feet.

What are the risk factors?
Spider vein risk factors are similar to those associated with varicose veins, including older age, occupations requiring extended periods of standing, obesity, heredity factors and hormonal changes. People can also suffer from this condition because of weak vessel walls or from exposure to ultraviolet rays.

Considering the risk factors, some people will be more prone to this problem than others. For example, if you work as a surgeon, a nurse or a teacher, the chances are higher that you might experience this condition. Similarly, for people with a genetic history of weak vein valves, the probability of developing spider veins is also high. The same applies to hormonal changes, which generally occur during puberty, pregnancy and menopause.

The exact cause of spider veins is yet to be established. Existing risk factors can be divided into two wide sub-divisions, i.e. acquired causes and congenital. In congenital causes, we have port-wine stain, Maffucci’s syndrome and hereditary hemorrhagic telangiectasia (also known as osler-weber-rendu syndrome), among others. The acquired causes include acne rosacea, chemotherapy and lifestyle/occupation risk factors (as mentioned above).

What symptoms are associated with spider veins?
Spider veins are painful in some cases, with cramping and aching. They often result in a feeling of heaviness in the legs, and burning, throbbing or tingling sensations. In addition, symptoms such as itching, fatigue and swelling can also be experienced. In advanced cases, this condition can establish ulcers, large sores and phlebitis. However, spider veins are noticed by their appearance in a majority of incidences.

Tests and Diagnosis
Doctors normally use non-invasive diagnostic tests to diagnose this condition. These tests are perfectly safe and painless, with no scalpels, needles or medication being involved. The entire procedure is normally very brief, and generally won’t take more than one hour from start to finish.

There are three main questions that doctors seek to answer through these diagnostic tests. Firstly, they wish to establish any evidence of deep vein blood clots. Secondly, they ascertain if the veins are functioning properly. Lastly, they test the Greater Saphenous Vein (GSV) to determine whether it is working well or not.

A competent vein specialist will always undertake this exercise before treating your condition. Some of the procedures that you can expect include:

*Color-flow Duplex Exam – This is used to evaluate the anatomy of the affected veins. It determines the direction of blood flow, openings and blockages. This procedure is also important in the process of vein mapping (needed for skin deep problems).

*Bi-directional Doppler Exam – This is an ultrasound exam used to determine the speed of blood flow and whether it pauses during normal breathing. It also identifies whether the veins are working properly.

*Photoplethysmography – Phew! Don’t let this complicated medical word intimidate you. Photoplethysmography is basically a diagnostic procedure that determines the efficiency of your calf muscle pump.

*Pressure Calf Exam – In performing this exam, you’ll be asked to lie facing upwards with legs lifted higher than your chest. This diagnostic procedure identifies vessel blockages.

Treatment
After establishing the specific nature of your problem, the doctor will then outline the right treatment plan for you. There are several available options:

Sclerotherapy
This procedure involves the doctor injecting a saline solution into the affected veins. The solution results in damage to the affected vessel walls, causing them to swell and seal shut. Within several weeks the scar tissue will fade. The sclerotherapy procedure takes about thirty minutes, and has only mild side-effects. Though the injection may be a bit painful, the stinging sensation is usually gone within a few minutes.

Laser and Intense Pulsed Light
This treatment employs the use of a specialized device that focuses laser energy to the affected tissue. The procedure takes only 20 minutes, and has minimal side-effects.

Natural Remedies
Using natural remedies can mean the difference between undergoing medical procedures or not, and are valuable alongside medical treatment. Some recommended herbal remedies include:

*Horse Chestnut Seed – Studies show that this seed helps to improve blood circulation in the legs thus strengthening the veins and capillaries.

*Bilberry Extract – This herbal extract is known to stimulate new capillary formation thus strengthening the capillary walls.

*Butchers Broom – This herb strengthens veins.

*Gotu Kola – A very effective extract in addressing venous insufficiency, foot swelling and water retention. It therefore provides a good solution to spider veins found on the legs.

*Distilled Witch Hazel – This is directly applied on the affected areas using a cotton ball. Numerous clinical studies have shown that this extract can help strengthen blood vessels.

Caution: For health safety purposes, do not start using any herbal remedies without consulting a qualified doctor.

Spider veins prevention
Two of the most important things regarding the prevention of spider veins are eating a balanced diet and getting regular exercise. Eating a diet higher in fresh, raw fruits and vegetables than meat and convenience food is important, and if your job requires you to stand for a long time, you should regularly shift your body weight from one leg to another as well as standing evenly balanced.

To sum things up, the procedure of a spider vein removal is chosen by several key factors. Your doctor will choose the optimum treatment options based on the results obtained from the diagnostic tests. We hope that this article will provide all the necessary guidance you need in addressing this problem.
