FAQs

We’ve put together answers to the most commonly asked questions.

Raw Materials

Are the materials Macpac produce packaging in environmentally friendly & Recyclable?

We produce all our packaging in responsible materials that are made from recycled materials and are fully recyclable. We supply much of our packaging in Clear R-PET material that has a minimum of 80% recycled content and is 100% recyclable.

What materials do Macpac supply in?

We supply much of our packaging in Clear R-PET material that has a minimum of 80% recycled content and is 100% recyclable. The other materials we use such as HDPE / Eco Form and Jazz PET are all made from recycled material and are recyclable.

Does Macpac offer a biodegradable material option?

Macpac can supply packaging in a material called Breakdown PET which has the same characteristics as R-PET but with a tiny amount of additive added that allows the material to biodegrade in landfill should it ever reach end of life. The material is also as recyclable as standard R-PET containing a minimum 80% recycled content and is 100% recyclable.

Can Macpac offer coloured material options?

Subject to a MOQ Macpac can colour match to any pantone reference that a customer requires.

Does the clarity of my pack change if I choose a thicker material?

In general, the thicker the material, the deeper the tint of the material – there is always a slight tint to the material due to the level of recycled content.

How do I know what thickness of plastic I need for my packaged product?

This is dependent upon your own pack requirements and will be determined by the size and weight of your product, the durability in transit and on the shelf at the retail store. Advice from one of our sales engineers will guide you through the process.

Retail packaging / Electronics Packaging

(can apply to electronics and other markets too)

What is the difference between a Clam Pack and a Clamshell?

The simple answers is there is no difference at all. It is purely terminology and the use of two terms for the same type of packaging.

What is difference between a blister and a clam pack / Clamshell?

A blister pack is usually a clear plastic shell that is adhered to a printed backing card, whilst a clam pack (or clam shell) is usually a one piece hinged plastic packaging format with formed panel(s) into which your product and printed promotional insert / header card is encapsulated.

What are the differences between types of blister pack styles – direct seal, trapped blister, slide on blister?

A direct seal blister as its name suggests refers to a plastic shell sealed direct to the face of a specially treated printed backing card – whilst this is a very cost-effective method of packaging for high volume requirements, it is not suited for small production runs. The recyclability for direct seal blisters is greatly reduced compared to the other formats, as the adhesive and print remnants contaminate the plastic blister upon separation from the card, making it less easy to recycle.

A trapped blister (or sandwich blister) is a variation of the standard blister – it uses the same plastic blister formed shell, but is encapsulated within two pieces of card, this could be a one-piece fold over card, or as separate panels, of which the front panel would have a die-cut window through which the blister protrudes. In this way the seal of the blister is due to the adhesive coating on the two card panels – the plastic is not affected by the adhesive, so can be separated from the card very easily when it comes to recycling.

A slide on blister – also known as a folded flange blister consists of a formed cavity complete with extended flange area to the required dimensions of the backing card, to which folded edges along each side creates a groove into which the backing card can be slid into place. Whilst this is a very simple pack that can be easily fulfilled by hand, the retention of the card within the pack may require a staple or locking clip to prevent movement.

Do you need specialist equipment to seal blister or clam packaging?

This will depend on the type of pack:

Direct seal blisters – as the card is coated with a special adhesive that is only activated by pressure and heat, a specialist machine with jigs made to suit the shape of blister and card will be required.

Trapped blister – again can use a heat seal treated card, with the adhesive applied to the inside panels of the card, or a cold seal pressure adhesive can be used (often known as Latex coating) – for the latter, jigs may still be required to ensure the product remains stable when pressure is being applied. Hand pressure alone is not usually consistent enough to activate the seal over a large surface area, so it is recommended to use some form of roller assist.

Slide-on blisters and most clam packs can be manually fulfilled without the need of further equipment. If further security is required, then staples, tamper evident clips, self-adhesive labels, and full weld sealing can be offered as possible options.

Comparison in terms of ease of packing, ease of recyclability?

The ease of packing will depend upon your individual product requirements, available labour, required fulfilment time, all of which will determine whether the process requires a level of automation?
Where the plastic has no direct weld or adhesive contact to a different substrate such as foil, film lid, or backing card and therefore has no contamination, then in most instances the product can be recycled (subject to material type) within the normal household recycling stream.

What material do you make these in?

Most of the packaging for retail applications are made in clear material – Macpac took the decision to phase out PVC for environmental reasons over 10 years ago, so all standard and new customer bespoke packaging is made in RPET (Recycled Polyethylene Terephthalate) which is made from a minimum of 80% recycled content and is 100% recyclable.

Do you supply the printed insert / backing cards?

Whilst we do not manufacture in-house ourselves, we do have several collaborative partners who offer us exceptional bulk pricing, which means we can offer you a fully tailored service for all your packaging components.

Can the packs be clipped open and shut easily?

On many of the standard clam packs simple friction clips, or locking tabs enable the packs to be opened and closed, as necessary. For bespoke customer product we can design in features to suit your requirements

Can I have fully sealed packs to prevent pilferage?

Standard Surecel packs already incorporate a unique locking feature. This type of tab can also be introduced into bespoke designs. If fully weldable packs are required, then choice of material must be determined from the onset of a project, as only certain plastic materials are weldable.

Electronics Packaging

Is standard material static resistant?

No, standard RPET does not have static resistance, but it is possible to manufacture packaging for electronics with antistatic / dissipative / conductive additives if order volumes dictate.

Do you have any standard packs for memory cards / USBS / drives?

Yes, there are standard clam packs / Clamshells available for DDR3 / DDR4 / DIMM, SODIMM – whilst we have extensive knowledge in relating to USB, memory sticks, SSD drives and other computer related products, most are of a bespoke nature. Please contact the office on 0161 4421642 for more details and to discuss your requirement.

How long will the material remain static resistant?

This is always difficult to say as the antistatic property can dissipate over time – this will depend on storage and handling. Normally a 12 month use by date is realistic, but in a controlled environment we have seen instances where the shelf life has been several years.

Horticultural Packaging

Can you ship outside UK?

We ship into Europe and beyond, but you must contact the office to request a quote as shipping costs vary depending on product (weight) and delivery destination. Delivery lead times will vary depending on destination.

Will a square/round pot fit the same packs? (3P920’s 3P9s 3P915’s mainly)

Yes, usually our packs will hold square or round pot’s, but we suggest you request a sample first to trial and test, samples are FOC for UK customers, there may be a carriage cost for destinations to Europe and further afield.

Postal Packs – do they need additional packaging?

No – our Plantpac postal packs are manufactured in a thicker material than our clamp pack range, if you add additional protection/packaging to these they will not go through as a large letter postage. Please add your postage and address label only and do not overfill.

Clamp Pack / Clamshell range – can I post these directly or do they need additional packaging?

Our Plantpac packs will need additional packaging as they have been designed to contain the plants and protect them, but they are not strong enough on their own, or designed for this purpose.

Do you have larger packs?

The largest pack we currently produce – the 1P15 – will hold a single 15cm diameter pot with foliage. We can also do bespoke packaging if required, please contact us to discuss further.

What is the minimum order quantity?

For all off the shelf products then we can supply by the single box QTY, the actual QTY will vary depending on the product size and box fill. See our on-line shop for more details.

For bespoke packaging with dedicated production runs then our MOQ is 1000 packs.

How much does tooling cost for bespoke packs?

This will depend on several factors including quantity required and complexity of design. Macpac has its own in-house design team and tooling manufacturing facilities, so please call, and speak to someone to discuss your requirements in more detail, and they will then advise you on tooling cost

Are the packs recyclable?

All R-PET supplied by Macpac has a minimum of 80% recycled content and is 100% recyclable.  The R-PET has virgin outer layers with the central middle layer containing the recycled content.
