Production of Plastic Packaging is a Daunting Task

 
Plastic packaging is essential for the safe and secure transportation of products from the manufacturer to the consumer. It must be product-specifically designed to ensure protection against damage or leakage while adhering to stringent regulatory requirements - such as those related to pharmaceuticals and food contact applications.  Additionally, it needs to meet specific marketing specifications around aesthetics, cost efficiency & weight consideration, amongst others; with plastic categorized generally into soft (lightweight) or rigid varieties.

Plastic packaging materials are prone to moisture absorption.

  1.  Polyethylene (PE) and polypropylene (PP): These materials have a high moisture absorption rate, especially under stress.
  2. Polyvinyl chloride (PVC): This material has a moderate moisture absorption rate but is prone to moisture absorption if it is not adequately stabilized.
  3. Polystyrene (PS): This material has a low moisture absorption rate, but it can still be affected by moisture if it is not properly protected.
Improper Drying of Plastic Packaging Material can lead to

Fish-Eye-Mark

Fish Eye Marks

Fish eye marks are minor, circular marks on the surface of flexible plastic packaging caused by contaminants in the material. They typically appear as raised, circular marks with a concave centre, resembling a fish's eye.
Blister-Mark-2

Blister Marks

Flexible packaging material is prone to blistering, but this often happens due to resins that haven't been dried properly. Identifying and addressing the culprit can help you avoid raised, rounded marks on your materials' surfaces - all by running resin through a dryer before moulding!
Air-Bubbles

Air Bubbles

Excessive moisture can have a detrimental effect on materials, resulting in issues with finished products. Such problems include reduced flowability during packaging and weakened stability, which can lead to collapses or wrinkles as well as potential defects like voids and sink marks - all of which will produce unwanted air pockets or bubbles
Uneven-Wall-Thikness

Uneven Wall Thickness

Moisture in the resin can hinder flowability, resulting in irregular wall thickness during processing. This could lead to uneven areas of thinner or thicker material than desired.
Reduced-Strength-and-Stiffness

Reduced Strength and Stiffness

The material loses strength and flexibility by absorbing moisture as water molecules displace polymer ones. This can result in reduced final product quality as it collapses or wrinkles, leading to lost stability and durability of what could have otherwise been achieved.
Degradation-of-Polymer

Degradation of Polymer

Moisture triggers various chemical reactions in materials, such as cross-linking and depolymerization. As water molecules displace polymer molecules within the material, its strength and stiffness are weakened - leading to cracking or splitting if left unchecked. This can cause severe damage over time due to the degradation of key additives in the material.
Flow-Lines

Flow Lines

Flow lines are a frequent nuisance in plastic packaging due to high moisture levels. These unsightly ripples, which their contrasting colour can identify against the surrounding product area, may appear on its surface or around specific entry points like “gates". Keep an eye out for these deformations and take preventive measures!
Decreased-Surface-Quality

Decreased Surface Quality

Moisture can cause the surface of the finished product to become rough or uneven, leading to a poor visual appearance.
Decrease-Processability

Decreased Processability

Moisture can cause the resin to stick to processing equipment, leading to problems with the processing of the material.
Other common problems faced by Plastic Packaging Industry are

Resin-conveying

Resin Conveying

Injection moulding is a rapid procedure, and Extrusion, an ongoing process, necessitates consistent material feed into the machinery. Between these processes, manually monitoring resins on the shop floor can become excessively intricate - primarily when large extruders are employed. This manual input has the potential to lead to human error with hazardous spillage of materials or resulting delays in changeover working times, making regular oversight laborious even over extended periods.
Mould-Sweating

Mould Sweating

Mould Sweating is an unwelcome occurrence in the moulding process, leading to significant issues such as rust formation, decreased productivity and quality deterioration. Not only does this negatively affect both expensive machinery and moulds, but it can also cause defects in moulded components, negatively impacting the process's efficiency. From rusting machines, prematurely aged moulds, and even components suffering defects - this uninvited issue hampers productivity in every measure imaginable.
over-Drying

Over-Drying or Poor Drying

Over-drying or poor drying of plastic materials can cause a range of issues with the finished product, as it may not have been given enough time to dry correctly. Temperature and air circulation must also be monitored during drying in order to ensure that moisture is removed efficiently from the material. It's essential too that any contamination caused through handling should be checked for before starting the process in order to avoid potential problems down the line.

Bry-Air Solution

Achieving a dew point of at least -40 º C during the material drying process is critical for ensuring optimal quality in moulded components.  Creating a lower vapour pressure on the surface of the resin lowers its moisture content and establishes an ideal condition to dry materials efficiently.  Temperature, drying time and airflow also play their part as it depends on what type of resin you are using — but if your ultimate goal is high-quality production results, then maintaining that minimum value can make all the difference!
