Washing line film

Types of washing line films

A washing line film is a packaging solution used during the final stage of product preparation before dispatch. It is usually used after intensive product washing and sterilization to ensure that every inch of the product is protected during transport to the retailer's shelf. In this context, a packaging film refers to any type of plastic film used to wrap, seal, or cover products for protection, containment, or presentation purposes.

Packaging films are typically divided into three types: flexible plastic films used to wrap or cover products, rigid films used as containers, boxes, or trays, and semi-rigid films that combine features of both flexible and rigid films. In the machinery industry, washing line films primarily refer to flexible films that are used to cove products before they are packed in boxes for retail.

Washing line films can be further subdivided based on their packaging style and technique:

• Wrap around: Usually, a non-perforated film is used to encompass an item, often secured with tape or stickers. It can be any size and is sometimes used for grouping multiple items together or for bundling.
• Flyback: Also known as a flyback restack. This is a method in which an item is wrapped in film that returns to the original starting point after being processed through a piece of equipment. The film is typically secured with a band or seal after the item has been wrapped in it.
• Reverse wrap: This is a type of wrap in which the product is wrapped with film that has the opposite side facing out than the one that is facing in. The term is also used to refer to wrapping methods in which the film is wrapped around the product in the opposite direction, usually involving "pulling" and "pushing" actions.
• Overwrap: A type of wrapping in which a film that is usually made of clear plastic is drawn tightly around a product or item, which is usually made of paper or other similar materials. This is commonly done to protect the product from dirt, moisture, and other contaminants, as well as to provide a tamper-evident feature and enhance the product's visibility.
• Collar wrap: This is a type of packaging in which a film is used to enclose an item, leaving a "collar" or unwrapped section at one or both ends. The collar is also known to provide easy access to the product and facilitate further processing or handling operations.

In the machinery industry, packaging films may also be categorized by their material composition. In this regard, films are usually made from materials such as polyethylene, polypropylene, polyvinyl chloride, polystyrene, and others. Moisture-resistant packaging is often made from packaging films like LDPE film.

Specification and maintenance of washing line film

The requirements for the specifications of films used in washing lines vary depending on the type of product, packaging, and consumer expectations. The critical factors in these specifications are the types, thicknesses, tensile strengths, sealability, UV resistance, cold-crack resistance, humidity resistance, transparency, clarity, colors, sizes, monument, and rewind size. Specialized washing line films are manufactured according to the demands of the product. It is essential to consult an expert to determine precisely what kind of washing line film is still in demand.

Washing line films are manufactured with specific characteristics, such as seal strength and UV, cold-crack, humidity, and transparency resistance. Seal strength is the capacity of a film to withstand specified tensile pressure when sealed. Seeing exactly what levels of seal strength and other resistances is essential before use, testing methods are available. International testing standards are used to ascertain these areas, including ASTM, ISO, BS, and SA testing methods.

UV or ultraviolent light is a segment of electromagnetic radiation with a wavelength between visible light and x-ray. It is germicidal, and many films contain UV inhibitors that block this harmful radiation. Cold-crack resistance is the ability of a film to remain flexible in extremely cold weather. Humidity resistance refers to the strength of the film when exposed to water vapor or moisture. In addition to these in-demand characteristics, it is essential to know whether the film is biodegradable. For example, Polypropylene (PP) is not readily biodegradable.

Biodegradability means that the film will break down into water, carbon dioxide, and biomass by the activity of naturally occurring microorganisms. Enterprises and customers prefer biodegradable films. It is essential to check the film for tears and any signs of damage and immediately repair or replace it. Store it in a dry, clean, air-conditioned environment away from direct sunlight. It should be out of reach of children and stored in a container that is not more than 75 full. Clean the container before use, and when using the film, make sure that the surface is smooth and that there are no wrinkles, rides, or distortions.

Washing line films should be kept away from harmful chemicals, anti-static, and dust. Always wash hands before handling the film, and when handling it, make sure to wear clean and dry gloves. Once the film is put into the machine, ensure its proper calibration. Practice on scraps before using them on valuable products to avoid damage or loss. When taking the product out of the machine, hold it firmly, and do not let it drop below 75% of its capacity to avoid bulletins and distortions. Always seek advice when unsure, as machinery and films can be expensive and unnecessary expenditure.

Scenarios

The washing film line serves multiple industries in various ways. Here are some of the common usage scenarios for film washing lines.

• Recycling Facilities

  Film washing lines are popular in recycling facilities and are often the backbone of such facilities. They are used to sort, wash, and transform various plastic films, like PE and PP, into reusable plastic pellets.

• Production Factories

  Garbage bag and plastic sheet production factories use film washing lines to recycle production wastage. This allows them to reduce produce costs and increase their profit margins.

• Municipal Recycling Programs

  Muni organizations engaged in plastic waste management may use film washing lines to handle plastic film collected from households, retail centers, and public places. The processed film can be sold to other organizations for further manufacture or kept for local use.

• Environmental NGOs

  Nonprofit organizations focused on environmental conservation may utilize film washing lines for educational initiatives. Instead of recycling plastic films for resale, they will use the films to educate the public on the environmental benefits of recycling.

• Exporting Companies

  Film washing lines offer a cost-efficient method of recycling plastic films. Many film-washing companies opt to process the films and sell the pellets to overseas companies for better profits.

How to choose washing line films

Choosing the right washing line film requires careful consideration based on specific needs, intended usage, and purchasing capabilities.

• Type of clothes:

  To begin with, it is crucial to determine the kind of items one typically hangs out to dry. Certain items, like delicate fabrics or clothing with unique requirements, may necessitate opting for a gentler washing line. Nevertheless, a standard line should suffice.

• Outdoor or indoor:

  A person's living situation is also a significant factor in determining which type of line is ideal. For those who can regularly enjoy outdoor drying, a durable line that can withstand the elements is essential, while those who typically dry indoors would benefit from a line that can easily be set up in an indoor space.

• Duration of use:

  The frequency of clothes washing should also be considered when selecting a washing line. For infrequent washers, a more economical option may suffice. In contrast, those who regularly launder clothes should invest in a durable line that can withstand frequent use.

• Budget:

  When selecting a washing line, it is crucial to focus on the features that matter the most and make a shortlist based on the desired characteristics. Additionally, it is essential to keep cost-effective options in mind. Many limitations can be easily overcome with creativity and flexibility, making it possible to find lines suitable for various situations at a relatively low price.
